Absolute value because for any number given the y or answer will be no less than 0 it will.always be positive
The product of 15 and

is

. This is a linear binomial.

is a cubic trinomial. In your original question, I'm not sure what the

means.
Answer:

Step-by-step explanation:
First, we can find the slope using the slope equation and two of the points.
Slope equation:

I'm going to use the first two points just so I can avoid the fraction... Substitute the x and y values into the equation.

Simplify:

Now that we have the slope, all we need is the y-intercept. Luckily, it gives it to us in the table. The x value of y-intercepts will always be 0. Looking at the table, we see that the point where x=0 is (0,2). Thus, the y-intercept is 2. Your final equation is

Children = .65 * people
people = 520 / .65
800 people were in attendance
