Question: how to find the slope of a line for dummies?
Answer: 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.
