Answer:
The equation of the linear function that best fits the data is,
<em>y</em> = 18.66<em>x</em> + 66.87.
Step-by-step explanation:
The line of best is of the form: <em>y</em> = <em>mx</em> + <em>b</em>.
Here, <em>m</em> = slope of the line and <em>b</em> = intercept.
The formula to compute the intercept and slope are:
Consider the table below for the values of <em>∑ X, ∑ Y, ∑ X² </em>and <em>∑ XY</em>.
Compute the value of intercept and slope as follows:
The line of best fit is:
Thus, the equation of the linear function that best fits the data is <em>y</em> = 18.66<em>x</em> + 66.87.

Answer:
............................
Step-by-step explanation:
Answer:
x = 9.5
this should be the right answer if the same one you had to solve.
Step-by-step explanation:
y = 2x - 4
y = 12 + 3 combine them
2x - 4 = 12 + 3
+4 +4 The 4's cancel each other out
2x = 12 + 7 Add then divide
2x = 19
2x = 19

x = 9.5
Answer:
x > 8
Explanation:
−2x + 12 < −4
[<em> Subtract 12 from both sides </em>]
−2x + 12 − 12 < −4 − 12
−2x < −16
[ <em>Divide both sides by -2 </em>]
-2x / -2 < -16 / -2
x > 8
