For you to be able to answer this you might need a tall numberline
Answer:

Step-by-step explanation:
If we have the equation
and we want to test if the point (4,–2) satisfies the equation, we can plug the x and y values into the equation and see if they make the equation true.
4 is the x value, -2 is the y.



So this does satisfy the equation.
Hope this helped!
I beleive that it would be C=n25
Step-by-step explanation:
I'm not sure if this is not complex enough but I'm just going by what I think this is.
P(x) =9x +30
the tips are a flat rate so it’s a constant 30 while the 9 per hour is dependent on the hours worked which is why it is attached to x as a coefficient
