Answer:
equation for left side:

equation for right side:

equation for top side:

equation for bottom side:

Explanation:
Slope intercept form is y=mx+b
m=slope
b= y intercept
Equation for left side:
We can find slope using points (0,2) and (1,5) in the formula



The y intercept is 2 since we see the line intersect the y axis at 2
So we fill in the equation with this information

Equation for right side:
Since the line is parallel to the other one then the slope will be the same which is 3
and to find y intercept we fill in the equation with what we know first

Now we fill in any point to find y intercept and I will use (4,2)

Now that we find b we put that into the equation

Equation for top side:
Since this is flat the slope is zero
and we can continue to find that the y intercept is at 5
and we can fill in this information and then simplify

Equation on bottom side:
Since this is also flat the slope is zero and we can see the y intercept is at -1
So once again we fill in what we know then simplify
