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

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

a =4/3   

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

x=6 and x=3
