I need help finding the function rule

Mathematics
1 answer:

Answer:

f(x) = - x + 20

Step-by-step explanation:

Start with x =0

that means that f(0) = 20

So

y = f(x)

y = ax + 20    Now if x = 1 , y = 18

18 = a(2) + 20 Subtract 20

18 - 20 = 2a     combine

- 2 = 2a            Switch

2a = - 2            Divide by 2

a = -2/2            Combine  

a = - 1            

y = - x + 20       Answer or

f(x) = -x + 20     Answer

Use technology to find the line of best fit for the following data.
likoan [24]

Given:

The data points are:

(1, 0), (2, 3), (3,1), (4,4), (5,5)

To find:

The equation of best fit line in the form of y=mx+b and then find the value of b.

Solution:

The general form of best fit line is:

y=mx+b              ...(i)

Where, m is the slope of best fit line and b is the y-intercept of the line.

Using the graphing calculator, we get the equation for the best fit line and the equation is

y=1.1x-0.7          ...(ii)

On comparing (i) and (ii), we get

b=-0.7

Therefore, the value of b is equal to -0.7.
