Math Problem Statement
The basketball gym at Kimi's school was built in the 1940s and needs a lot of repairs. So, the school is asking families for donations to build a new gym. Kimi convinced some local businesses to match a fraction of the families' donations. The businesses contribute $12 when a family donates $15. The businesses contribute $20 when a family donates $25. In this relationship, x represents the amount of money a family donates (in dollars), and y represents the matching contribution (in dollars) from local businesses. Graph two points for this relationship and the line passing through them.
