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)

Write the equation of the line in Point-Slope form that goes through the point (10,5) and has a slope of -3

• y= -3x + 35

• y + 5= -3(x + 10)

• y= -3x - 35

Which of the following lines goes through the point (0, 4) and is parallel to y = 5x - 3?
