Answer:
(9,3)
Step-by-step explanation:
I don't think any of the answer choices are correct 9/3 is
To solve this problem you must apply the proccedure shown below:
1. You have that the <span>data set has SSR=400 and SSE=100
2. Therefore you have </span><span>the coefficient of determination is:
r</span>²=SSR/SSTO
SSTO=SSR+SSE
3. Then, when you substitute the values, you obtain:
SSTO=400+100
SSTO=500
r²=400/500
4. So, you have that the result is:
r²=0.8
Therefore, as you can see, the answer for the exercise shown above is: <span> the coefficient of determination is 0.8</span>
Y < = 4x - 5 (thats less then or equal)....I think the equal goes in there too....it is hard to tell from the picture.....if it is a solid line, the equal sign is included...but for some reason it does not look the same as the other line (which for sure includes an equal sign)
y < = 2x + 3
Answer:
since slope(m) = y2 -y1/x2- x1
-5 - 9/ -3 - (-3)= -14/0
m = -14/0 (undefined)
using the formula
y-y1 = m(x -x1)
y - 9 = -14/0(x - (-3)
y-9 = -14/0(x + 3)
0 = -14( x+3). (cross multiplication)
0 = -14x - 42
14x = -42
x = -3( equation of the line)
