Explain how to do it step by step, it is about slope

•Slope is defined as "rise over run."
•Make sure that the line is straight. You can't find the slope of a line that isn't straight.
•Coordinates are the xand y points written as (x, y). It doesn't matter which points you pick, as long as they're different points on the same line.
•It doesn't matter which one you pick, as long as it stays the same throughout the calculation. The dominant coordinates will be x1 and y1. The other coordinates will be x2 and y2.
•Set up the equation using the y-coordinates on top and the x-coordinates on bottom.
•Subtract the two y-coordinates from one another.
•Divide the y-coordinate's result with the x-coordinate's result. Reduce the number if at all possible.

A) the rise in the roof is a reference to the change in the y axis in correspondence to the x axis, which is referred to as the horizontal change. to find the slope, put the rise 8 on the top and 24 on the bottom since the slope is the rise/run. The slope should be 1/3.
b) To find the slope for b), remember the formula y2-y1/x2-x1= slope. So minus y1(5) by y2(6) and divided by x2(2)-x1(3). The answer would be -1.
c) Rearrange the equation and you will find it's actually y=-9x+7, so the slope would be -9
