Answer:
The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65
Step-by-step explanation:
Let x be the number of t-shirts and y be the total pay
As we can clearly see in the table that there is a linear relationship between x and y
A linear function is given as:
![y = mx+b](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb)
Here m is the gradient of the function then
![m = \frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Taking any two pairs of x and y
(1,68) and (2,71)
![m = \frac{71-68}{2-1}\\m = 3](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B71-68%7D%7B2-1%7D%5C%5Cm%20%3D%203)
Putting in equation
![y = 3x+b](https://tex.z-dn.net/?f=y%20%3D%203x%2Bb)
Putting a pair (1,68) in the equation to find the value of b
![68 = 3(1) + b\\68 = 3+b\\b = 68-3\\b = 65](https://tex.z-dn.net/?f=68%20%3D%203%281%29%20%2B%20b%5C%5C68%20%3D%203%2Bb%5C%5Cb%20%3D%2068-3%5C%5Cb%20%3D%2065)
Putting the value of b
![y = 3x+65](https://tex.z-dn.net/?f=y%20%3D%203x%2B65)
Let p(x) be the linear function
Hence,
The linear function is: p(x) = 3x+65
3 and 3 1/5 because the median is always in the middle
