8-121.

**Multiple Choice:**Which line below is perpendicular to the line 2*x*− 5*y*= 3? Homework Help ✎2

*x*+ 5*y*= 7−2

*x*+ 5*y*= 45

*x*− 2*y*= −15

*x*+ 2*y*= 3

Two lines are perpendicular if their slopes are negative reciprocals.

Put each equation, including the one in the problem, into slope intercept form.

Solve for *y*.

2*x* − 5*y* = 3

−5*y* = −2*x* = 3

Solve for *y*.

Solve for *y*.

Solve for *y*.

Solve for *y*.

Correct!
