HELP ME 10 points I NEED HELP TIMED

A line passes through the points (8,-1) and (-4, 2).

What is the y-intercept of this line?

-4
-1
1
4 ?????!

Answer 1

y = (-1/4)x + 1 so that the y-intercept is 1

Explanation:

The slope is (-1 - 2)/[8 - (-4)] = -3/12 = -(1/4)

(-1/4) = (y - 2)/(x + 4) => -x - 4 = 4y - 8

-x + 4 = 4y

y = (-1/4)x + 1 so that the y-intercept is 1
