you can find the slope of the two lines...when it is perpendicular m1*m2=-1 m1=one of the slope m2=the second slope if you multiply the slopes together, you will get -1 if it is perpendicular.

Math
you can use a substraction-or-addition method or substitude method. So... x+y=21 you multiply both side by 3 3x+3y=63 3x+4y=21 --------- then you eliminate one variable you use the subtraction method -y=42 y=-42 then you solve for x by substituting the y x+(-42)=21 x=63
