Question

Select the correct answer.
Which equation represents the horizontal line passing through (9,-7)?
X = 9
y = 9
x = -7
y = -7

Answer 1

Answer:

y = - 7

Step-by-step 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 (9, - 7 ) with y- coordinate - 7 , then

y = - 7 ← equation of line
