Which of these systems of equations shows the solution for the graph? Question 5 options:

A)

y = 5∕2x + 4; y = –1

B)

y = –5∕2x + 4; y = 1

C)

y = –5∕2x + 4; y = –1

D)

y = –5∕2x –4; y = –1

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

answer is (b.
