Answer:
The linear regression model is
.
Step-by-step explanation:
The given data points are (-6 4) (-4 0) (-3 -2) (-1 -7). Plot these points on a coordinate plane.
From the graph it is clear that the point are in the form of a straight line, so we need to use the linear regression model.
The general linear regression model is

Using technology we get


Put a=-2.19 and b=-8.92 in the above equation.

Therefore the linear regression model is
.
Answer:
Its is 85
Step-by-step explanation:
It is 85 because you need to see out of all of those numbers which one is one is in the middle so just mark one number from each side untill you get to the middle number!
3X+9X=180
12X=180
X=15°
Angle 1=3X
Angle 1 =45°
That's your answer.
