So you have yo turn it into the correct form first so you add 4x to both sides and come out with 2y=4x-12 them you divide each side by 2 because you have to have to by itself and you come out with y=2x-6 so the slope is 2x and the y intercept is -6
(-1,2) is where it will intersect
The difference based on the numbers given is -80.
<h3>How to compute the difference?</h3>
The information given illustrates that the difference will be:
= (9 - 1) - (43) - (2 - 3) - 50
= 8 - 43 - (-1) - 50
= 8 - 43 + 1 - 50
= -80
Therefore, the difference or subtraction among the numbers given is -80.

Answer:
With alpha 0.95 and 8 degrees of freedom χ²= 2.73
And with alpha 0.05 and 8 degrees of freedom χ²=15.51
Step-by-step explanation:
The significance level ∝ = 1- 0.9 = 0.1
But we need the area of the middle so we divide this significance level with 2
so that we get exactly the middle area .
Dividing 0.1/2= 0.05
So we will have two values for chi square
One with 0.9 + 0.05 = 0.95 alpha and one with 0.05 alpha . This is because the chi square is right tailed.
So with alpha 0.95 and 8 degrees of freedom χ²= 2.73
And with alpha 0.05 and 8 degrees of freedom χ²=15.51
This can be shown with a graph.
I think it would be 7.5!!
