Question

Lines RS, TV, and SW are shown.

On a coordinate plane, 3 lines are shown. Line R S goes through (negative 8, 6) and (2, 6). Line T V goes through (negative 6, negative 4) and (8, negative 4). Line S W goes through (2, 6) and (2, negative 8).
Which statements are true about these lines? Select three options.

Line RS has a slope of 6.
Line SW has an undefined slope.
Line TV has a slope of 0.
Lines RS and TV are parallel.
Line SW is perpendicular to line RS, but not to line TV.

Answer 1

True statements (three):

- Line SW has an undefined slope. (vertical line x = 2)
- Line TV has a slope of 0. (horizontal line y = -4)
- Lines RS and TV are parallel. (both horizontal)

Reason: RS and TV are horizontal so slope 0 and parallel; SW is vertical so slope undefined and perpendicular to both horizontal lines.
