Answer:

y = 10x

Step-by-step explanation:

y = amount earned

x = time ( hours )

40 = 10x

divide by 10 you get

x = 4

she worked for 4 hours

You can use this equation for any amount of time.

How do you find the constant of variation when y=-(2/3) and x=3
Katyanochek1 [597]
You can't. If you think about the straight line on a graph, those numbers
describe a single point that the line goes through, and they don't tell you
anything about the slope of the line, or where it crosses the x-axis or the
y-axis.  So I don't think you can tell the constant of variation from one point.
