8-121.
  1. Multiple Choice: Which line below is perpendicular to the line 2x − 5y = 3? Homework Help ✎

    1. 2x + 5y = 7

    2. −2x + 5y = 4

    3. 5x − 2y = −1

    4. 5x + 2y = 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.

2x − 5y = 3

−5y = −2x = 3

Solve for y.
