Answer:
Step-by-step explanation:
Given that the population of a city increased steadily over a ten-year span. The following ordered pairs show the population x and the year y over the ten-year span in the form (x, y) for specific recorded years.
x y
2500 2001
2650 2002
3000 2004
3500 2007
4200 2011
Slope 0.005865485
Intercept 1986.406413
So regression line is
When population = 15000

Answer:
Step-by-step explanation:
A = -2.2
E.
( -2.1 ) + ( - 0.1 )
( -2.1 ) - 0.1. <—— over there, you will see that + is gone and the - has moved down, I done that because + plus with - equals to -.
-2.1
-0.1
———-
-2.2
Answer:
y = x + 2
Step-by-step explanation:
The expression x-2 is from the equation y = x - 2.
To find the inverse of the equation, <u>switch the "x" and "y" variables</u>, then solve or <u>isolate for "y"</u>, meaning to separate it from the other numbers.
y = x - 2 Original equation
x = y - 2 Switched "x" and "y" variables
x + 2 = y - 2 + 2 Add 2 to both sides to cancel out '-2' on the side with "y"
x + 2 = y
y = x + 2 Variable is on left side in standard formatting
To isolate, do the reverse operation for the number you want to get rid of.
On the side with "y", I wanted to get rid of '-2' so I could separate "y" from everything else. '+2' is the reverse operation for '-2'.
