Answer:
A. 1/2
Step-by-step explanation:
You have to do the slope formula which is ..
[tex]\frac{Y_{2}-Y_{1} }{X_{2} -X_{1} }[/tex]
Once you input the coordinates into the formula, it should look like this..
[tex]\frac{7-2}{1-(-3)}[/tex]
You solve that and you'll get [tex]\frac{2}{4}[/tex] which can be simplified to [tex]\frac{1}{2}[/tex]
