[tex]-\frac{4}{7}[/tex]

Step-by-step explanation:

Slope = [tex]\frac{-3-5}{7-(-7)}[/tex] = [tex]\frac{-8}{14}[/tex] =[tex]-\frac{4}{7}[/tex]

the answer is -4/7.

you would first find the difference of the y values which equals -8. then you find the difference in x. this equals 14. since y goes over x that would be -8/14. this can be simplified to -4/7.
