Question

Write an equation in slope-intercept form (y = mx + b).

A vertical line passing through (1, -4).

Answer 1

x=1

Explanation:

Anytime there is a vertical line, the y value becomes infinite as the line goes on forever. The only restriction on the line is on the x value of your coordinate. The same goes for a horizontal line, only the x value would become infinite and the y value would be constant.

Vertical Line: (x,∞)

Horizontal Line: (∞,y)
