Answer:

B (4)

Step-by-step explanation:

[tex]\frac{9+7}{3+1}[/tex] = [tex]\frac{16}{4}[/tex] = [tex]\frac{4}{1}[/tex] = 4
Answer B



This is because you use the formula
Y2-y1
———-
X2-x1

So you would take Y2 which = 9 then subtract y1 which is -7 This equals 16

Then you take x2 which is 3 and subtract -1 which equals 4

Then you take 16/4 which equals 4
