Answer:

Let's find the equations of the lines using the given slope and point.

9. m = 5 and (6, -1):

Using the point-slope form of a linear equation (y - y1) = m(x - x1), where (x1, y1) is the given point and m is the slope:

(y - (-1)) = 5(x - 6)

y + 1 = 5(x - 6)

y + 1 = 5x - 30

y = 5x - 31

11. m = -2 and (4, 1):

Using the point-slope form:

(y - 1) = -2(x - 4)

y - 1 = -2x + 8

y = -2x + 9

12. m = -4 and (-3, -3):

Using the point-slope form:

(y - (-3)) = -4(x - (-3))

(y + 3) = -4(x + 3)

y + 3 = -4x - 12

y = -4x - 15
