y = -2x + 9 Step - by - step explanation: We first need to find the slope m = (y2 - y1) / (x2 - x1) = (9-5) / (0-2) = 4 / -2 = -2 We will use the slope intercept form of a line y = mx + b where m is the slope and b is the y intercept y = -2x + b We know that 9 is the y intercept since x is equal to zero y = -2x + 9
