I can’t tell from the blanks — you didn’t include the equations or the slope values. To decide whether two lines are perpendicular use this rule:

- Two nonvertical lines are perpendicular iff their slopes are negative reciprocals (m1 · m2 = −1).
- A vertical line (x = a, slope undefined) is perpendicular to a horizontal line (y = b, slope 0).

How to get a slope:
- From slope-intercept form y = mx + b the slope is m.
- From standard form Ax + By + C = 0 the slope is −A/B.

If you post the two line equations (or the slopes shown in the choices), I’ll tell you which choice is correct.
