WTF, IMHO, LOL, and ROFL don't make sense until they have been explained to you. It's the same for the letters commonly used in algebra. Once you know what they represent, then you can easily understand what is being written. In simplest terms, another way of saying y = mx+ b is, what is the numerical value of y if x is ... Without diving deeply into a complicated explanation (for which I was confusing myself) let me tell you what the letters mean in y = mx + b. This is the generic equation that will produce a straight line when the results are depicted graphically on a two-dimensional graph. "y" is the answer to the calculation. Its value depends on the value of the other letters and the arithmetic applied to them. Its value can change depending on the value of x. Therefore, we call "y" a dependent variable. The values of the letters m and b remain the same in each particular equation. They are called constants, and I'll explain them in a moment. The value of "x" can change to anything. Most often some of its values are known and from them we can use the equation to find out what '"y" would be for a value of "x" we haven't measured. Because "x" can be anything, we call it an independent variable. What about "m" and "b"? The value of these remains the same for a particular equation. Their job is to describe the direction and location of a line which joins all the values of "x" plotted on a graph. The letter "m" determines the angle the line makes with the horizontal axis of the graph. That angle is known as the "slope". It can be calculated from a graph by "run over rise", where "run is the horizontal distance between two points and "rise" is the vertical distance between them. The greater the value of "m", the steeper the slope of the line. Also, if "m" is a positive number, the line rises front left to right across the graph. If it is a negative number, it falls from left to right. The letter "b" determines where the straight line will cross the vertical axis of the graph. If the value of "b" is zero, then the line will cross the Y axis at the "origin", which has the values of zero for both "x" and "y". If "b" has a positive value, then the line will cross the vertical axis at the point on the axis where the value of "x" is zero and the value of "y" is the same as the value of "b". Here's a diagram which puts that all together. Graphs of equations where "x" is just a plain number are straight lines. If 'x' is squared, cubed, or a square root, the graph will have some sort of regular curved shape. Often in practice the graph of "y" versus "x" will not be so plain, as in torque and horsepower graphs. That's when interpreting them will involve calculus, and I'm not going there! 1

red750 Posted October 3 Author Posted October 3 An oldie, but still a chuckle... A woman awakes during the night to find that her husband is not in bed. She puts on her robe and goes downstairs to look for him. She finds him sitting at the kitchen table with a hot cup of coffee in front of him. He appears to be in deep thought, just staring at the wall. She watches as he wipes a tear from his eye and takes a sip of his coffee. ☕️ 'What's the matter, dear' she whispers as she steps into the room, 'Why are you down here at this time of night?" The husband looks up from his coffee, 'It's the 20th Anniversary of the day we met'. She can't believe he has remembered and starts to tear up. The husband continues, 'Do you remember 20 years ago when we started dating, I was 18 and you were only 16,' he says solemnly. Once again, the wife is touched to tears. 'Yes, I do' she replies. The husband pauses The words were not coming easily. 'Do you remember when your father caught us in the back seat of my car' 'Yes, I remember' said the wife, lowering herself into the chair beside him. The husband continued. 'Do you remember when he shoved the shotgun in my face and said, "Either you marry my daughter or I will send you to prison for 20 years'. 'I remember that, too' she replied softly. He wiped another tear from his cheek and said "I would have gotten out today." 1

Popular Post red750 Posted October 8 Author Popular Post Posted October 8 A young couple were killed in a car accident and were met at the Pearly Gates by Saint Peter. "Welcome to Heaven. Before you come in, do you have any questions?" "Yes" says the girl, "We were going to get married but didn't get the chance. Can we get married in heaven?" "That's a good question ," said St Peter. He thought for a while, then said, "I'll go and find out for you." While the couple sat and waited, they thought about various things. They realised they would be in Heaven for eternity. Eternity is a very long time. After six weeks, St Peter returned. "I've got good news. Yes, you can get married in Heaven." The girl said, "We've been thinking. Eternity is an awfully long time. What if we don't want to be married any more? Can we get divorced in Heaven?" St. Peter looked perplexed and said, "It took me six weeks to find a priest. How long do you think it will take to find a lawyer?" 5
