Answer:
B (for question 7)
Step-by-step explanation:
To find the slope, we use the equation [tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex].
m = (-4+1)/(7+2) = -3/9 = -1/3
Since B is the only option that would give a slope of -1/3, B must be the answer.
(you can use this same method for question 8)
