Question

Choose the equation of the horizontal line that passes through the point (−5, 9). (1 point) x = 9 y = 9 x = −5 y = −5

Answer 1

Answer: y = 9

Explanation:

Horizontal lines are parallel to the x-axis and are drawn left to right. However, the equation of a horizontal line looks like this
`y=a`.

So it's easy to eliminate x = 9 and x = -5 because those equations represent a vertical line. Vertical lines are parallel to the y-axis and are drawn up and down.

I provided a picture example of a graph so you can understand why its y = 9 and not y = -5

Answer 2

y = 9

Explanation:

the equation of a horizontal line is

y = c ( c is the value of the y- coordinates the line passes through )

the line passes through (- 5, 9 ) with y- coordinate 9 , then

y = 9 ← equation of horizontal line
