When put in matrix form, the coefficients of
... 3x -2y = 7
... x + 4y = 2
look like
The determinant is 3×4 - 1×(-2) = 14.
Answer:
Step-by-step explanation:
(a)
perfect positive correlation.
As x increases by 1, y increases by 1
y is 1 times x
equation: y = x
(b)
perfect negative correlation.
As x increases by 1, y decreases by -4
y is times x
equation: y = -4x
