Question

The slope of a line is undefined, and the x-intercept is -7. What is the equation of the line?

Oy=-7
Ox=-7
Oy=-7x

Answer 1

"Undefined slope"

Explanation:

The line is vertical on the graph.

Every point on the line has the same x-coordinate.

If the line crosses the x-axis where x=-7, then the

x-coordinate of every point on the line is -7, and the

equation of the line is

x = -7 .
