MARKING BRAINLIEST!!! Please help..

Karen is trying to choose a cellphone plan. Company J charges a subscription fee of $30 per month plus $1 per hour of use.
Company K charges no monthly fee, but charges $3 for every hour of use. Karen made this graph to compare the prices of the two plans....

The lines for company J and company K cross a point.
The coordinate (30,60) is the point at which company J and company K cost the same. What does the point (30,60) mean? (Hint: What is being graphed on the x-axis?

What is being graphed on the Y-axis?).

If Karen used her cell phone for less than 30 hours a month, which company should Karen choose? Why?

IF Karen uses her cell phone for more than 30 hours a month which company should she use? Why?
