Using a calculator, the slope of the line of best-fit is of 7.2.
<h3>How to find the equation of linear regression using a calculator?</h3>
To find the equation, we need to insert the points (x,y) in the calculator.
In this problem, the points are given as follows:
(-4,-32), (-2,-8), (0,10), (2,8), (4,32).
Using the calculator, the equation is:
y = 7.2x + 2.
Hence the slope is of 7.2.

Answer:
12 Newtons
Step-by-step explanation:
We can use Newton’s Second Law to find the mass first.
F = ma
9 = 3m
mass = 3
Substitute this into the second equation.
F = ma
F = 3(4)
F = 12N
Hope this helps! :D
Step-by-step explanation:
If you can get 3 shirts for $24 then that means that each shirt was $8. With that being said, 8 multiplied by 7 equals 56 so you would pay $56 for 7 shirts.
Answer:
f = - 
Step-by-step explanation:
Given f varies directly with m then the equation relating them is
f = km ← k is the constant of variation
To find k use the condition f = - 19 when m = 14
- 19 = 14k ( divide both sides by 14 )
- 
= k
f = - m ← equation of variation
When m = 2 , then
f = - × 2 = -
