Question

Which of the following best describes the graph of the following linear equation?

y − 9 = -9

Horizontal line with y-intercept at (0,0)

Vertical line with y-intercept at (0,0)

Vertical line with x-intercept at (18,0)

Horizontal line with x-intercept at (9,0)

Answer 1

Horizontal line with y-intercept at (0,0)

Explanation:

y - 9 = -9

Adding 9 to both sides:

y = 0

So it is the x axis.
