Question

Find the equation of a line whose y-intercept is 6 and is parallel to x-axis.

Options

• y = 6

• x = 6

• x + y = 6

• y − x = 6

Answer 1

y = 6

Explanation:

A line parallel to the x-axis has:

Slope (m) = 0

y-intercept (c) = 6

Substituting the values in equation y = mx + c, we get:

y = 0x + 6

y = 6
