Question

which of the following represents a line parallel to X axis?

1) x + y = 7

2) x + 3= 0

3) y + 2= 2y - 5

4) 5x +3 = 4

Answer 1

Answer: (3)

Step-by-step explanation:

Parallel lines have same slope.

The slope of x- axis ( y=0) = 0

Slope $\frac{a}{b}$ of the following lines are:

1. 1
2. ∞
3. 0
4. ∞

Therefore line (3) is parallel to x-axis.
