(a) (3, 13) and (7,45) Using the two-point formula and the procedure demonstrated in Example 11, 32-yi 45 13 32 7-3 4 m= =8 then substituting m = 8. x13, and y = 13 in the point-slope formula y-y=m(x-x1) (b) (2. 18), (5,-3) y-13 8(x-3) y=8x-11 -3-18 -21 M= = =-7 5-2 Using m=-7, x1 = 2, and y = 18 in the point-slope formula, y-18 -7(x-2) y=-7x+32 (c) (3.-17), (0, 19) 19-(-17) m= = 0-3 36 3-12 With one of the points (0, 19) the vertical intercept, the equation can be written immediately. (d) (0, -2). (8.0) y=-12x+19 0-(-2) 2 1 8-0 8 4 With (0,-2) the y intercept, y=
