Miguel has his heart set on a new GPS that will cost him $325 if he pays cash and $400 if he pays by installments. If the down payment is $50, how much will he pay in
each of 12 monthly payments? What is the annual interest rate on this purchase?

(-1,-0.5)

step-by-step explanation:

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: 72: 111
