Step-by-step explanation:
Given
The attached graph
Required
Determine the line equation
First, list out two points from the graph


Next, calculate the slope (m)




The equation in slope intercept form is:

This gives:


Open bracket

Let us try and solve it analytically. We have that the side=x+3 together with the short side=s and the diagonal=x+4 satisfy the Pythagorean Theorem. Then we have that

. This yields

which yields s^2=2x+7, hence a) is the correct answer.
