Slope-Intercept Form
3
m = 3, b = -7 B)y = 2/3x y = 2/3x + 0 m = 2/3, b = 0 C)y = 5 y= 0x +5 m = 0, b = 5
4
Put it in slope-intercept form. (Solve for y.) -3y = -5x + 6 y = 5/3x - 2 m = 5/3, b = -2
5
B) 4y + 2 = 2x *Put it in slope-intercept form. (Solve for y.) 4y = 2x - 2 y = 2/4x - 2/4 m = 1/2, b = -1/2

Example 5: You can use a laser or inkjet printer to print an 18-page report. The laser printer prints 6 pages/ minute and the inkjet printer prints 4.5 pages/ minute. The models give the number of pages p left to print after t minutes. laser: p = -6t + 18 inkjet: p = -4.5t +18 a) Graph both models in the same coordinate plane. b) How many minutes do you save using the laser printer?
