Answer:
So the slope of this function is
and the y-intercept is 
Step-by-step explanation:
A first order function has the following format:

In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.
We have the following equation:

We just have to rewrite this equation



Which means that

So the slope of this function is
and the y-intercept is 
Answer:
50 minutes
Step-by-step explanation:
1/2 hour = 30 minutes
1/3 hour = 20 minutes
30 + 20 = 50 minutes
There are many solutions. infinite solutions at that. when you solve it it equals itself 2.5w+21= 2.5w+21 so that means all numbers would work as a solution.
Well if there are 231 tickets, then divide 231 by three, that will equal 77, so if you see what i am doing,i am diving all tickets by 3 so that the students get 2/3 and the adults get the pther 1/3. so the answer is 77.
Answer:
2
to find the slope you get the rise which is the difference between the y coordinates over the run which is the difference between the x coordinates. so 6/3=2
