Answer:
1. Use slope to determine how steep, and in what direction (upward or downward), a line goes. Finding the slope of a line is easy, as long as you have or can set up a linear equation. This method works if and only if:[1]
2. Find the number in front of the x, usually written as "m," to determine the slope. If your equation is already in the right form, {\displaystyle y=mx+b}y=mx+b, then simply pick the number in the "m" position (but if there is no number written in front of x then the slope is 1). That is your slope! Note that this number, m, is always multiplied by the variable, in this case, an "x."
3. Reorganize the equation so one variable is isolated if the slope isn't apparent. You can add, subtract, multiply, and more to isolate a variable, usually the "y." Just remember that whatever you do to one side of the equal sign (like add 3) you must do to the other side as well. Your final goal is an equation similar to {\displaystyle y=mx+b}y=mx+b.
Explanation:
By Picking two points on the line and determining their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
