Answer:

(b) y = 9

Step-by-step 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 (1, 9 ) , with y- coordinate 9 , then

y = 9 ← equation of horizontal line

The equation of the horizontal line passing through the point (1,9) is B. y = 9.

A horizontal line has a constant y-coordinate.

This means that no matter what the x-coordinate is, the y-coordinate remains the same.

In other words, all points on a horizontal line have the same y-value.

In this case, the y-coordinate of the given point is 9.

Therefore, the equation of the horizontal line passing through this point is y = 9.

No matter what the x-coordinate is, the y-coordinate will always be 9.

So therefore the correct answer is B. y = 9.
