7. what is the slope of the line that passes through the pair of points (3, 8) and (9, 5) ? (1 point) (a). -2 (b). 2 (c). 1/2 (d). -1/2 8. what is the slope of the line that passes through the pair of points (-7/2, -3) and (-5, 5/2) ? (1 point) (a). 6/22 (b). -6/22 (c). 22/6 (d). -22/6 10. write an equation in point-slope form for the line through the given point with the given slope (1 point) (5, 2); m = 3 (a). y + 2 = 3 (x - 5) (b). y + 2 = 3x - 5 (c). y - 2 = 3 (x + 5) (d). y - 2 = 3(x - 5) 11. write an equation in point-slope form for the line through the given point with the given slope (1 point) (-4, -2); m = -1/2 (a). y + 2 = -1/2(x - 4) (b). y + 2 = (-1/2)x - 4 (c). y + 2 = -1/2(x + 4) (d). y - 2 = -1/2(x - 4)
