Question

Find an equation that passes through the points (2,4) and is perpendicular to the line 3x+4y-22=0

Answer 1

Hello:
the equation is : y = ax+b
the slope is a : a×(-3/4) = -1......( perpendicular to a line :

3x+4y-22=0 : another equation is : y = (-3/4)x +22/4 with the slope : (-3/4))

a =4/3

an equation is : y - 4 = (4/3)(x-2)
