Question

what is the equation of the red line pictured below?
o x=2
o y=2
o y=2x
o y=x+2

Explanation:

Step1: Identify line - type

The red line is horizontal. For a horizontal line, the equation is of the form $y = k$, where $k$ is a constant.

Step2: Determine the y - value

The red line intersects the y - axis at $y = 2$. So the equation of the line is $y=2$.

Answer:

y = 2
