Answer:
B: y=-3
Step-by-step explanation:
We are given a graph
We have to find the value of given graph
Horizontal line: That line which is parallel to x -axis.
Equation of horizontal line
y=a
Vertical line: That line which is parallel to y- axis
Equation of line : x=b
From given graph we can see that a horizontal line that cuts the y- axis at -3.
So, given graph is y=-3
Hence, option B is true.
