Now that we know the equation of a line, which is y=mx+b, we can now graph it. How do we graph it? It's pretty easy. First you graph the b variable, which is the y-intercept. You look on the y axis and look for that number. After you find it, you put a dot on it. Next you need to graph the mx part, which is the slope of the line. It is called the rise over run because you go up and then go to the right. If it is negative, you go down and then go right. The slope of the line looks like it is going up hill. If it is negative, the slope of the line will go down hill.
What I learned was how to graph the equation, y=mx+b. When I first learned it, it was pretty hard. The variables would just confuse me. Once I got help from my teacher, it was just easy. Sometimes we would have to find the b variable and sometimes we would have to find the mx part. To find the m part, this is the equation to find it which is delta y over delta x. What that means is y2-y1/x2-x1. That is how you find m if you have two points like (0,5) and (9,4). To find b, you input one of the points into the y=mx+b equation. So it would look like 4=m(9)+b. You would multiply the m with the x and then subtract 4 and add the mx part to get b.
