Question

Georgie joins a gym. She pays $25 to sign up and then $15 each month. Write it. Use your graph to find a solution. Label it. Write your answer as a sentence.

Answer 1

Equation: y = 15x + 25

Ordered pair: (2, 55)

Explanation:

1) Set up the following as a linear equation. A linear equation can also be used to graph data or create a table containing the data.

2) A linear equation is in the following format:

y = mx + b

mx represents the slope

b represents the y-intercept

3) Since Georgie pays 25 dollars to sign up, the y-intercept would be 25.

Since Georgie pays 25 dollars to use the service, this number would be the slope.

4) y = 15x + 25

Y, represents the total amount Georgie has spent.

5) One solution of this would be (2,55)

Simply pick any x value to input and using the y value received as the outcome form the ordered pair.
