Use the slope formula: $m=(y_2-y_1)/(x_2-x_1) = (1/5-5)/(-1-7) = 3/5.$

There is a formula for the slope of a straight line, given two points $(x_1,y_1)$ and $(x_2,y_2)$ on the line:

$m=(y_2-y_1)/(x_2-x_1)$

It doesn't actually matter which points we choose as points 1 and 2, because the formula will give the correct answer either way.

I've calculated the answer above using this formula.

How do you find the slope given the points (7,5 )(7,5 ) and (-1, 1/5)(-1, 1/5)?
