Question: how to find the slope from the x and y intercept?
Answer: Using your example, suppose the X-Intercept is 8 and Y-Intercept is 11. Then we know that (8,0) and (0,11) are points on this line. Therefore, the slope of the line is ΔyΔx, or the change in y over the change in x. Therefore, slope=0−118−0=−118.
