Question 3 • 2025-2026_MDCPS_1205070-M/J Grade 8 Pre-Algebra Sem 1-CR
Marissa researched the cost to have custom T-shirts printed by several local and online vendors. She found that each store’s charge for the job could be modeled by a linear function that combined a flat charge for artwork with a per T-shirt rate. Marissa plotted the functions on a coordinate grid and found that two of the functions produced lines that had the same y-intercept. How should Marissa interpret this result?
Answer
A
Those two vendors charge the same rate per shirt.
B
Those two vendors charge the same flat rate for artwork.
C
Those two vendors will have the same total cost to produce one shirt.
D
Those two vendors will charge the same total cost for any size job.
Explanation
In a linear cost function, the y-intercept is the cost when the number of T-shirts is zero. That represents the flat artwork charge, so the vendors with the same y-intercept charge the same flat rate for artwork.
