During the summer, Hector does yard work, and Geri babysits.To show their earnings, Hector makes a graph, and Geri makes a table

VLD [36.1K]

I think that when you asked this question, no one answered because there is not enough information. I also got this problem and there is in fact, a table and a graph.

Step-by-step explanation:

for Hector, it only shows a y and x graph and for Geri it shows a table. let´s call the graph the ¨h¨ graph (for Hector) and the table is going to be called the ¨g¨ graph (for Geri)

on the h graph, it shows that y/x = dollars/time for Hector,

on the g table, it shows that Geri is getting paid $25.50 for each 3 hours and it keeps increasing within each input and output.

your y = your dollars

your x = your time

we are looking for slope and we need $15 over hours

15/x

the answer is that Hector earns $6.50 more than Geri
