Start with
y = mx + b
Now use the 2 given points to find m and b.
7 = m(0) + b
b = 7
1 = m(3) + 7
m = -2
f(x) = -2x + 7
Answer: A
Step-by-step explanation:
The coefficient of determination is a number between 0 and 1 used to measure the level of precision with which the regression model created fits the data. A measure of means that the model explains the entire variation between the two variables without error.
Therefore, in this case, if means that the 9 points are on the line
