Write the equation of the line.
Slope = -4, passing through (-1, 5)

• y+5 = -4(x-1)

• y-5 = -4(x+1)

• y-5 = 4 (x-1)

• y = -4x - 9

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 +7 = -1/4(x - 4)

• y - 4 = -1/4(x + 7)

• y+ 7 = 4(x - 4)

• y - 7 = -1/4(x - 4)
