Unformatted text preview: 32d. slope = 40 (The cost of making each coat is $40.) 37a. y = .10x + 160 37b. y = .10(1000) + 160 y = $260 37c. 500 = .10x + 160 x = $3400 62. The equation of the line is y = 23250x + 580,000 When x = 8 (2008), y = 766,000 *You were given 2 points in this problem. Utilize the slope formula and the point-slope formula to get the equation of the line....
