John buys a new bedroom set on credit for $2760 and no interest. he pays $115 per month. what is the equation that models the money john owes?

Suppose that the equation is modeled by a linear equation:

let the amount owed by John, is y at time time, x.

the linear equation is given by:

y=mx+c

where:

m=slope

c=y-intercept

from the information:

c=$2760

m=$115

thus amount owe will be:

y=-115x+2760
