What is the x and y intercept for the following equation ? 4x - 10y = 20

Work needs to be turned in on a piece of paper. No work = no credit.

• x - int = (0 , 5)    

  y-int = (-2, 0)

• x-int =(0 , -2)

  y-int = (5, 0)

• x - int = ( 5 , 0)

  y int = (0 , -2)

• x -int = (-2 , 0)

  y -int = (0, 5)

Write the equation in POINT-SLOPE form of the line that passes through the point (7, -4) and has a slope of -1/4,

• y +4 = -1/4(x - 7)

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

• y - 7 = -1/4(x + 4)
