Answer:
They are perpendicular
Step-by-step explanation:
the first graph has 1/3 as its slope.
The inverse of 1/3 is the negative reciprocal, or -3/1, which is the same as -3.
Thus, as the second graph’s slope is -3, it is the inverse of the first graphs slope, which means the two graphs represent lines which are perpendicular to each other.
