mia had $40. then she started to receive $5 a week as an allowance. she plans to save all of her money for a bicycle and draws a graph of her planned savings. mia lets x represent the number of weeks she has received her allowance, and y represent her total amount of money. which of the following ordered pairs is on mia’s graph?
(1, 40)
(4, 60)
(2, 80)
(6, 30)

Explanation:

Step1: Form the linear equation

Mia's total savings $y = 40 + 5x$ (initial $40 + $5 per week $x$).

Step2: Test each option

• (1,40): $y=40+5(1)=45≠40$ → No
• (4,60): $y=40+5(4)=60$ → Yes
• (2,80): $y=40+5(2)=50≠80$ → No
• (6,30): $y=40+5(6)=70≠30$ → No

Step3: Confirm the correct pair

Only (4,60) satisfies the equation.

Answer:

B. (4, 60)
