ANSWER: [tex]\frac{2}{-5}[/tex]
EXPLANATION:
We can use the slope formula and input the x and y values to solve for the slope.
[tex]\text{Slope Formula}: \frac{y_{2}-y_{1} }{x_{2}-x_{1}}=m[/tex]
[tex]\frac{5-3}{2-7}=m\\\text{Simplify.}\\\frac{2}{-5} =m[/tex]
The slope of the line is [tex]\frac{2}{-5}[/tex]
