Question

Hello,

This is a question in my algebra homework. how would I find the slope of two straight lines when given no points and just the lines on a graph. I also attached my question to this.

Thanks,

Answer 1

These lines should have opposite reciprocal slopes because they seem to be perpendicular. Pick 2 points from one line first, write the slope formula, name the points going from left to right. To this to each line
The slope formula:
m=(y2-y1)/(x2-x1)
