Which line is perpendicular to the line passing through the points (-4,2) and (4,-4)a. 3x+4y=16b. 3x-4y=4c. 4x+3y=15d. 4x-3y=9e. 3x+4y=-4

Answer»

To find c, put the values of X, y and m as 3, 4, -1.33. Thus 4 = -1.33*3 + c, or 4 = -4+c, or c = 8. Hence the EQUATION of the LINE is 4x+3y=8 and that will be parallel to 4x+3y=12.
