Question

Which equation would represent the line with a slope of zero and the point (2,4)?

x = 2

x = 4

y = 2

y = 4

Answer 1

y = 4

Explanation:

A line with slope of zero is a horizontal line. Every point on a horizontal line has the same y-coordinate. Since the line includes the point (2, 4) whose y-coordinate is 4, then all points on this line have y-coordinate 4.

The equation is

y = 4
