Question

The temperature on a particular day started at –13°F. It rose steadily by 3° each hour. The function y = –13 + 3x models the temperature, where x is the number of hours and y is the temperature. Graph the equation.

Graph your y-intercept (-13) first then graph according to slope. Remember ride over run so you would go up 3 and over 1 to find your next point
