Zachary purchased a computer for $1,500 on a payment plan. Four months after he purchased the computer, his balance was $960. Six months after he purchased the computer, his balance was $690. What is an equation that models the balance y after x months?
The equation hh models the balance y after x months
(Type your answer in slope-intercept form. Use integers or fractions for any numbers in the equation. Do not include the $ symbol in your answer.)

y=-135x+1500

Step-by-step explanation:

first you see that the starting point of the equation in $1500( y-axis) which would be the b part of the equation

Next you would take (4,960) which is at 4 months he had $960 left and (6,690) where at 6 months he had $690 left.

You would do change of y over change of x to get -135 as your slope

then you would plug in the finial equation y= -135x(slope)+ 1500( your starting point)

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

answer is 144
