Hailey wants to buy an expensive dress for her senior prom. She already saved $150, and she keeps saving $2 from her allowance every day.
Create and graph the equation that models the total amount Hailey saves, y, in terms of the number of days she adds to her saving, x

Respuesta :

Answer:

y = 2x + 150

Step-by-step explanation:

The initial value is $150, this is the y intercept as this is the amount she has at day 0.

To calculate the gradient use change in Y/change in X. the question says that there is an increase of $2 each day so the gradient is 2.

Since y = mx + c we can replace m and c for 2 and 150 to get y = 2x + 150
