graph charges vs hours. Is it a line?
Now to examine it with your mind, look at the gap between 1 and 2 hours. The change of one hour (1 to 2) is 15 dollars (from 35 to 5o). Now look at the gap between 3,4: a change of one hour is 20 dollars. and from 2 to 3, one hour increase is 20 dollars.
so here are the slopes
So it appears at first glance, that the "service call" is 5 dollars, then the rate per hour is 20. PLOT IT.
The table shows how much a painter charges for painting a home. Is the relationship shown linear?
Explain.
Hours worked is the left side and Amount Charged is the right side.
1| 35
2| 50
3| 70
4| 90
I'm not understanding what to do first
