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 in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

• y + 1 = -3(x - 2)
• y + 1 = -3(x + 2)
• y - 1 = 3(x - 1)
• y + 2 = -3(x + 1)

Write an equation  
m = 5/4 through (-4, -3)

• y = 5/4x +2
• y = -5/4x + 2
• y = 2x - 5/4
• y = 3/4x + 2

Write an equation 
m = 1/3 through (4, 4)

• y = -1/3x + 8/3
• y = 8/3x - 1/3
• y = 8/3x + 1/3
• y = 1/3x + 8/3
