Question

1. sean plans to start taking an aerobics class.

7a nonmembers pay $4 per class.
write an equation in the form ( y = mx + b ) to represent the monthly cost, ( y ), as a function of the number of classes taken, ( x ).
( y = 4x )
7b members pay a one - time $10 sign - up fee but only have to pay $2 per class.
write an equation in the form ( y = mx + b ) to represent the monthly cost, ( y ), as a function of the number of classes taken, ( x ).
enter your next step here

Explanation:

Step1: Identify m and b

In \( y = mx + b \), \( m \) is the slope (rate per class), \( b \) is the y - intercept (fixed cost). Here, \( m = 2 \) (cost per class for members), \( b = 10 \) (one - time sign - up fee).

Step2: Write the equation

Substitute \( m = 2 \) and \( b = 10 \) into \( y=mx + b \). So the equation is \( y = 2x+10 \).

Answer:

\( y = 2x + 10 \)
