Step-by-step explanation:
Slope = change in y over the change in x
Slope = (y2 - y1)/(x2 - x1)
Slope = rise over run
You can pick any two points on a line to calculate the slope.
You can double check your answer by trying different points on the line.
If the line is going up, from left to right, the slope is positive.
If the line is going down, from left to right, the slope is negative
