Write the equation in point-slope form of the line that passes through the given point and has the given slope.

(4, -7); m = -1/4

• y = -1/4(x - 4) - 7

• y = -1/4(x + 7) + 4

• y = 4(x - 4) - 7

• y = -1/4(x - 4) + 7

Write the equation in point-slope form for the line that contains the points

(-2, -3), (4, 3)

• y = 1(x - 2) + 3

• y = 1(x + 2) - 3

• y = -1(x + 2) + 3
