Determine the equation of the line that passes through the given points. (If you have a graphing calculator, you can use the table feature to confirm that the coordinates of both points satisfy your equation.) (3, 18) and (8, 33) a. y = 3 x + 9 b. y = negative 3 x minus 9 c. y = 3 x + 18 d. y = negative 3 x + 9
