Question

What is the equation of a line that has a slope of zero and goes through (2, 5)?

y = 2
x = 5
y = 5
x = 2

Answer 1

y = 5

Explanation:

A line with a slope of zero is a horizontal line parallel to the x- axis.

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line passes through

The line passes through (2, 5) with y- coordinate 5, thus

y = 5 ← equation of line
