Answer:
A. The r²-value of the linear model is greater than 0.977
Step-by-step explanation:
A P E X
8x-9y=19
4x+y=-7
Multiply all terms of the 2nd by (9)===> 36x + 9y= 63
add (36x 9y= 63) to the 1st ===> 44x+0y = -44 ===> x=-1
replace x by this value in any of the equation & you'll get y=-3
Answer:
C.
Step-by-step explanation:
m1 is greater than m2 because the angle is larger
