Section: Quantitative Aptitude

Question : 130 of 200

Marks: +1, -0

y = 10

Solution:

Concept:

Lines that are parallel have the same slope. Convert each line to slope-intercept form

y = mx + c

and compare slopes.

Explanation:

Given line:

6x - 2y = 10

can be written as

y = 3x - 5

. So its slope is

3

Option A:

3x - y = 4

becomes

y = 3x - 4

. Slope is

3

Option B:

y = 3x - 1

has slope

3

Option C:

y = 4x + 5

has slope

4

Option D:

12x - 4y = 9

becomes

y = 3x - \frac{9}{4}

. Slope is

3

Only option C has a different slope, so it is not parallel.

Answer:

y = 4x + 5
