Question

Write the equation of a line that is parallel to

y
=
9
y=9y, equals, 9 and that passes through the point
(
3
,
−
8
)
(3,−8)left parenthesis, 3, comma, minus, 8, right parenthesis.

Answer 1

The equation of the line is
`y=-8`

Explanation:

we know that

The equation of the line
`y=9` is a horizontal line (parallel to the x-axis)

The equation of a horizontal line is equal to the y-coordinate of the point that passes through it

In this problem, the line passes through the point (3,-8)

The y-coordinate is -8

therefore

The equation of the line is
`y=-8`
