Question

What is the equation of a horizontal line passing through the point (2, 10)?

Answer 1

`y = 10`

Explanation:

All horizontal lines have the equation `y = ....`

The y-value will stay the same, no matter what x-value is used.

The given point `(2,10)` gives us the y-value as 10.

The equation is `y = 10`

In slope/intercept form this would be `y = 0x+10`

The slope is 0, and the y -intercept is 10.
