Answer:
Slope is 4/5
Step-by-step explanation:
The two points are (3,3) and (-2,-1)
The slope formula is Y2-y1 / x2-x1
So substituting in
-1-3/ -2 -3
-4/-5 = 4/5
You can check it by "walking" up 5 and over to the right 4 on the graph and see that it works.

Answer:
sample variances
Step-by-step explanation:
The pooled variance method is used to estimate the variance of several different population with different means, but are assume to have the same variance.
The weights represent the sample variances.
So the correct answer is
sample variances
