1.

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

Answer»

ind 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.
