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
