Question

A line goes through the point (–2,3) and has a slope of –4. What is the y-intercept of the line?

Answer 1

y intercept= -5

Explanation:

You use the formula y-y1 = m(x-x1)

then you put in the points given to find the y intercept

y -3 =-4 (x - - 2 )

y-3 = -4x -8

+3 +3

y= -4x -5

This means that when the slope is -4 then the y intercept is -5

Answer 2

-5

Explanation:

y-3=-4(x+2)

y-3=-4x-8

y=-4x-5
