Question

Which of the lines is perpendicular to the line shown in the graph

Answer 1

Answer:

The line passing through (-8, 10) and (-1, 4).

Step-by-step explanation:

Two lines are perpendicular if the product of their slopes is -1. The slope of the line in the picture is $7\over 6$, so we should find a line with slope of $-6\over 7$.

Note that the slope of the line in the last option is $-7\over 6$.
