Pedro is buying a car for $15,500. He is borrowing money at a rate of 7.5% for 8 years. How much interest will he pay on the car? Simple interest formula is I = prt

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

is the anwser b. (-13)?
