Question

m/j accel math gr 7-zielske (lms)
topic 4 assessment (lms graded)
cost ($) vs number of cookies graph with points (2, 1.50) and (6, 4.50).
options:
(2, 1.50)
(3, 2.50)
(4, 3.50)
(5, 4.50)
(6, 4.50)

Explanation:

Step1: Find the slope of the line

The line passes through (0,0) and (6,4.50). Slope $m = \frac{4.50 - 0}{6 - 0} = 0.75$.

Step2: Verify each option

Check if $y = 0.75x$ holds:

• (2,1.50): $0.75×2=1.50$ ✔️
• (3,2.50): $0.75×3=2.25≠2.50$ ❌
• (4,3.50): $0.75×4=3≠3.50$ ❌
• (5,4.50): $0.75×5=3.75≠4.50$ ❌
• (6,4.50): Typo (space in 4 50), correct is (6,4.50): $0.75×6=4.50$ ✔️

Answer:

(2, 1.50), (6, 4.50)
