Work Step by Step

Here, we must choose two slopes that are opposite reciprocals. For this problem, we will choose 1 and -1. Since y = mx+b, where b is the y intercept, we can choose any non-zero value for b (since the equation cannot go through the origin). We will choose 5. Thus: $y = -x+5$ and $y = x+5$
