Equations Quiz (5 Questions)

1. Find equation of line parallel to y = 3x + 2 passing through (0,0).

2. Find equation of line perpendicular to y = −2x + 5 passing through (2,1).

3. True or False: Parallel lines have the same slope.

4. Slope of line y − 3 = 1/2(x − 4)?

5. Give a real-life example where equations of parallel/perpendicular lines are used.

Answer Key

1. y = 3x

2. Slope = 1/2 → y − 1 = 1/2(x − 2) → y = 1/2 x

3. True

4. 1/2

5. Road intersections, engineering layouts, building designs, railroad tracks
