The graph for a stable that charges a $20 flat fee plus $10 per hour for horseback riding is shown below. How will the graph change if the stable changes its charges to a flat fee of $45 plus $30 per hour?

To find the new graph we need to remember the equation of a line in its slope-intercept form
[tex]y=mx+b[/tex]In our case m will represent the charge per hour and b will be the flat fee.
Then the new charge will be described by the equation
[tex]y=30x+45[/tex]The graph of this equation is
