What does the y-intercept mean in the context of this
problem?

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

the answer is a if my teacher taught me correct

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

69.64%
