Answer:

Input variable x: Number of classes he attends.

Output variable y: Monthly cost

Slope: Cost per class, of $2

y-intercept: Membership fee, of $25.

Function: y = 2x + 25

Step-by-step explanation:

This situation can be represented by a function is the following format:

y = mx + b

In which y is the monthly cost(output), m is the cost per class(slope), x is the number of classes he attends(input) and b is the membership fee(y-intercept).

We have that:

There is a membership fee of $25 per month and a fee of $2 per workout class he attends.

This means that b = 25, m = 2. So

y = 2x + 25

Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of ?
Darina [25.2K]

Answer:

y – 2 = (x – 3)

Step-by-step explanation:

because (3, 2) was the point used for the equation but turned negative because you need to make it negative for the equation. y - y1 =m(x - x1)

Determine the x- and y-intercepts of the graph of y=−1/3x+3 .
Alinara [238K]

Answer:

x intercept

y = 0 \\ 0 =  \frac{1}{3} x + 3 \\  \frac{1}{3} x =  - 3 \\ x =  - 9

y intercept

x = 0 \\ y =  \frac{1}{3}  \times 0 + 3 \\ y = 3

The table shows the values of a function f(x).
QveST [7]

Answer:

The average rate of change is =-4

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is given by;

=\frac{f(b)-f(a)}{b-a}

We want to find the average rate of change of the function represented in the table  from x=-2 to x=2.

=\frac{f(2)-f(-2)}{2--2}

From the table f(-2)=25 and f(2)=9

The average rate of change from x=-2 to x=2 is

=\frac{9-25}{2--2}

=\frac{-16}{4}

=-4
