Here's the question you clicked on:

What is the slope between the two points (8, 15) and (3, 5)? What is the x-intercept and y-intercept of the graph of 10x - 5y = 20?
You have two points so you can find the slope using m(slope) = (y2-y1)/(x2-x1)
As for the second question..... X and y intercepts are where the graph of a line crosses the x-axis and the y-axis. At every point on the x-axis y = 0. So by setting y =0 in your problem, and solving for x, you can find the x-intercept. By setting x=0 and solving for y, you can find the y-intercept
Totally confused! Lol

That should help. Try plotting you two points so you can see how it works as well.
