Answer: Cya
Step-by-step explanation:
30-2 = 4x
28 = 4x
Divide both sides by 4 to eliminate the 4.
x=7
<span>It means that the point lies directly on the regression line.

(m+2)(m+3)= (m+2)(m-2)
⇒ m^2+ 3m+ 2m+ 6= m^2 -4
⇒ 5m+ 6= -4 (m^2 on both sides cancels out)
⇒ 5m= -4-6
⇒ 5m= -10
⇒ m= -10/5
⇒ m= -2
The final answer is m=-2~
Left side goes up 5 right side goes up 7
The rate of change between 5,15 is 10
