Dylan took out a loan for $3150 at a 7.2% APR
compounded monthly, to buy a video projector. If he will
make monthly payments of $188.50 to pay off the loan,
which of these groups of values plugged into the TVM
Solver of a graphing calculator could be used to
calculate the number of payments he will have to make?
O A. N=;1% = 0.6; PV=-3150; PMT=188.5; FV=0;
P/Y=12; C/Y=12; PMT:END
O B. N=1% = 7.2: PV=-3150: PMT=188.5; FV=0;
P/Y=1; C/Y=12; PMT:END
O C. N=;l% = 0.6; PV=-3150; PMT=188.5; FV=0;
P/Y=1; C/Y=12; PMT:END
O
D. N=;1% = 7.2; PV=-3150; PMT=188.5; FV=0;
P/Y=12; C/Y=12; PMTEND

N= ; I% = 7.2; PV=–3150; PMT=188.5; FV=0; P/Y=12; C/Y=12; PMT:END

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
