Answer
$m=1$
Work Step by Step
To find the slope, we use the formula $m=\frac{y_2-y_1}{x_2-x_1}$.
We plug in the $x$ and $y$ values given to us in the coordinate pairs: $m=\frac{3-1}{7-5}$
We simplify above and below the fraction bar with subtraction: $m=\frac{2}{2}$
Then, we divide the fraction: $m=1$
