Question

-x + 5y = -15

Answer 1

That's impossible to solve without a second equation. In that case, x and y could be an infinite number of pairs.

Answer 2

Find the coordinates of the x-intercept.
-x + 5y = -15 this is the question

Answer 3

Ah ok. Well the x intercept is when the line crosses the x axis which is when y is equal to 0. So put y as zero and you should get x = 15.

Answer 4

ok, thanks
