Entry Test MCQs # 1 – Mathematics

Correct Answer: (B) y = −2x + 4

Explanation:
Parallel lines always have the same slope. Since line L₁ has slope −2, the slope of line L₂ will also be −2. The general equation of a line is:

y = mx + c
where:

• m = slope
• c = y-intercept

The line passes through the point (0,4). When x = 0, the value of y = 4. Therefore the y-intercept c = 4. Substitute values:

y = −2x + 4

Hence, the correct answer is (B) y = −2x + 4.
