Sample Questions

1multiple correct

Which of the following represent equations of lines parallel to the x-axis? (Select all correct answers)

Show answer

y = 5, y = -2, y = 0

Lines parallel to x-axis have the form y = k (constant). They have zero slope and run horizontally. Lines of form x = k are parallel to y-axis.

2multiple correct

Which conditions must be satisfied for two lines to be perpendicular? (Select all correct)

Show answer

Product of slopes = -1, Slopes are negative reciprocals

For perpendicular lines: m₁ × m₂ = -1, which means slopes are negative reciprocals of each other (m₂ = -1/m₁).

3multiple choice

Convert the equation 3x - 4y + 8 = 0 to slope-intercept form.

Show answer

y = (3/4)x + 2

Rearrange to y = mx + c form: 3x - 4y + 8 = 0 → -4y = -3x - 8 → 4y = 3x + 8 → y = (3/4)x + 2.

4multiple choice

Find the equation of line passing through points (0, 2) and (3, 8).

Show answer

y = 2x + 2

Slope = (8-2)/(3-0) = 6/3 = 2. Since line passes through (0,2), y-intercept = 2. Therefore, y = 2x + 2.
