the first one is -11,-5,2,6,19
Here, we know 1/2 = 0.50
So, the difference between 0.50 & 0.26 is 0.24
And difference between 0 and 0.26 is 0.26
1 is very apart from 0.26 as compared to other two
So, It is closer to 1/2
Hope this helps!
The point-slope form:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
m - slope
x₁, y₁ - the coordinates of a point
It passes through the points (1,-2) and (2,2).
![(1,-2) \\ x_1=1 \\ y_1=-2 \\ \\ (2,2) \\ x_2=2 \\ y_2=2 \\ \\ m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-(-2)}{2-1}=\frac{2+2}{1}=4](https://tex.z-dn.net/?f=%281%2C-2%29%20%5C%5C%0Ax_1%3D1%20%5C%5C%20y_1%3D-2%20%5C%5C%20%5C%5C%0A%282%2C2%29%20%5C%5C%0Ax_2%3D2%20%5C%5C%20y_2%3D2%20%5C%5C%20%5C%5C%0Am%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%5Cfrac%7B2-%28-2%29%7D%7B2-1%7D%3D%5Cfrac%7B2%2B2%7D%7B1%7D%3D4)
Just divide 40.25 by 3.5. You get 11.5. So his pay rate is 11.5 every hour.
I hope this helps :)
