Question

Anya is saving her allowance to purchase a bike. Anya started her savings with $10 and is saving $5 per week. Let y represent the total amount Anya has saved and x represent the number of weeks Anya has been saving.

Select two points to graph the line.

Question 8 options:

(0, 15) and (1, 10)


(0, 0) and (10, 15)


(0, 0) and (15, 10)


(0, 10) and (1, 15)

Answer 1

y = 10 + 5x

Explanation:

The question seem incomplete as the question requirement is not stated.

However, I'll solve for the equation and also plot the graph that illustrates the equation.

From the question, we have the following.

Base Amount = 10

Additional = 5 (weekly)

Let y represents her savings at any given weeks and x represents the number of weeks

y is calculated using

y = Base Amount + Additional * weeks

y = 10 + 5 * x

y = 10 + 5x

Next, it to plot the graph.

Take x = 0

y = 10 + 5 * 0

y = 10 + 0

y = 10

Take x = 3

y = 10 + 5 * 3

y = 10 + 15

y = 25

So, the graph must pass through

(0,10) and (3,25)
