making a linear equation and graphing it based on a car loan

Question

for a project i am evaluating financing a car the principle of the loan is $99,057 with interest included , the monthly payments are $2,751.60 per month. and its being financed out for 3 years, how would i plug the numberes in L(x)=mx+b in order to graph it, find the slope,y-intercept, and domain / range? HELP!

Answer 1

L(x) (money owed) = - 2751.6x + 99057

x is months

slope is -2751.6

Domain is x=0 to 36

Range is 0 to 99057
