Question

how do i solve #13? (linear equations)

Answer 1

#12:

Assuming that I have those points correct: (1, 5) and (-4, -10), the slope of this line is

5-(-10)

m = --------------- = 15/5 = 3

1-(-4)

The line passes thru the origin, so the y-intercept is 0.

So the equation of this line is y = 3x.

I see no marks (points) in the illustration for #13.
