3x+5y=8
5x-3y=5
Answer by tutor_paul(519) (Show Source): You can put this solution on YOUR website!
Put each of these equations into y=mx+b form. m is the slope:
Equation #1:
Slope of Equation #1 = -3/5
=================
Equation #2:
Slope of Equation #2 is 5/3
=================
You can see the slopes are negative reciprocols of each other. Hence, the lines are perpendicular.
=================
Good Luck,
