What is the y intercept of y= -5 + 7

For a better understanding of the explanation given here, please find the diagram in the file that has been attached.

The expression given to us is . This can be rewritten as .

This is in the form y=constant where the constant is 2.

Now, we know that whenever the straight line is of the form y=constant, then the straight line will be a horizontal line parallel to the x axis at a distance which is the value of the constant.

The y intercept of such a line is always the point (0, constant).

Thus, the y intercept of the expressions given to us will be (0,2) as shown in the graph of the file attached.

i believe the answer is the polygon, heptagon.
