Answer 3

\(slope=\large\frac{y_2-y_1}{x_2-x_1}\)

Answer 4

Answer 5

It is already been given to you in the plot

Answer 6

I'm guessing stuff in the hours worked & the amount charged

Choose whichever you want, but they have to be two distinct points.

let hours worked be x and amount charged be y
