Question

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?

Answer 1

You have two points so you can find the slope using

m(slope) = (y2-y1)/(x2-x1)

Answer 2

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

Answer 3

Totally confused! Lol

Answer 5

That should help.

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

Answer 6

okay thank you.
