Answer: 
= 0.89
Step-by-step explanation:
Coefficient of determination is represented by . This tells us that how much of the variation in the dependent variable is explained by the independent variable.
It is the ratio of explained variation by the independent variables to the total variation in the dependent variable.
Hence,
Coefficient of determination = 
= 
= 0.89
∴ 89% of the variation in the dependent variable is explained by the independent variables.
Answer:
a) -2 and 4
b) function 2
Step-by-step explanation:
a)
rate of change is rise over run: change in y / change in x.
function 1:
- i will use first 2 pairs of data
- change in y: 5 - 3 = 2
- change in x: -2 - (-1) = -1
-rate of change = 2/-1 = -2
function 2:
- same idea, but find two points on the graph!
- (0,4) and (-1,0) for example! pick easy points
- change in y is 4. chabge in x is 1
- rate of change is 4
b)
function b has greatest rate of change. 4 > -2
You could use 10, 6 and 7.
Using ten would have them all equal 50, using 6 would have them all equal 30 and using 7 would have them all equal 35.
Hope this helps!

Answer:
9/2
Step-by-step explanation:
