James earns a monthly salary of $1200 and a commission of $125 for each car he sells. Graph an equation that represents how much James earns in a month when he sells x cars.

Use the slope-intercept formula: y=mx+b; you’ll get that

y=125x+1200

where "y" is the total value

125 is "m" or the rate of change

and 1200 is "b" or the initial value, or the initial value

and "x" is the amount of cars
