Respuesta :

expression: y=80+15x
(x representing months) x=12
so at the end of the year he will have $260
so y=mx+b
m=slope
b=y intercept, or the value of y when x=0

when x=0 is when time=0

that is initila value of 80

b=80


the slope is the increase per time unit
that is 15
so m=15


y=15x+80 is da equation where x is number of months elapsed



at the end of the year is 12 months elapsed
x=12
y=15(12)+80
y=180+80
y=260

after 1 year, he has $260
