Answer:
[tex]y=10x[/tex]
Why:
To express a question like this, remember slope intercept form. Remember it is [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept. We know that for after every hour, the charge increases by $10, which means the slope is [tex]\frac{10}{1}[/tex], or 10. There is no y intercept, as y = 0 when x = 0.
