Question

The line that is parallel to the x-axis passes through the point (4,12) has the equation

a. y=3x
b. y=1/3x
c. y=12
d. x=4​

Answer 1

C

Explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

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

The line passes through (4, 12) with y- coordinate 12, thus

y = 12 → C
