Answer:
The value of m would be -1/5
Step-by-step explanation:
In order to find the m of the second line, we need to find the slope of the first line, which is 5. Now, the perpendicular slope would be the opposite and reciprocal. So we take 5 and we negate it to -5. Now we flip it to get -1/5, which is the slope of the new line.
