Answer:

  y = 5

Step-by-step explanation:

There are a number of ways to get there, but the short of it is that a horizontal line has the equation ...

  y = constant

The constant value must be chosen to match the y-value of points on the line. Here, that is 5. The equation of the line is ...

  y = 5

_____

Another way

You can write the equation in slope-intercept form if you know the slope and the y-intercept. The line crosses the y-axis at y = 5, so that is the value of the y-intercept.

The "rise" between the two points is 5 -5 = 0. The "run" between the two points is 5-0 = 5, so the slope is ...

  m = rise/run = 0/5 = 0

Then the slope-intercept equation is ...

  y = mx + b . . . . . where m is the slope and b is the y-intercept

  y = 0x +5

Simplifying, we get ...

  y = 5
