Can I get some help please?

Check whether the lines y = x - 7 andy y= -x + 2018 are perpendicular (Do not graph. Just investigate the slopes and justify conclusion.)

Find the slope of both lines. If the products of their slopes is -1, then the lines are perpendicular. If the product of their slopes is not -1, then the lines are not perpendicular. This is the test you must perform to answer the question.
