First find the slope using the two points (2,225) and (5,480) (480-225)/(5-2) = 85 Then find b. 225 = 85*2 + b 225 = 170 + b 55 = b y = 85x + 55 OR f(x) = 85x + 55 This is the answer to PART B. Standard form PART A is 85x - y = 55 PART C Plot the y intercept, 55. From the y intercept count the slope 85 up right 1 and plot a point, draw a line through the points The x axis is the number of days so it would be in intervals of 1. The y axis is money, I would do intervals of $5
