To do this you can do (pay) x (hours) to work out how much Johnny makes for example:
8.25 x 29.5 = 243.375$ so the answer is 243.375$

Answer: The graph is attached.
Step-by-step explanation:
 The equation of the line in Slope-Intercept form is:
 
 Where "m" is the slope and "b" is the y-intercept.
 Given the first equation:
 
 You can identify that:
 
  By definition, the line intersects the x-axis when  . Then, subsituting this value into the equation and solving for "x", you get that the x-intercept is:
. Then, subsituting this value into the equation and solving for "x", you get that the x-intercept is:
 
 Now you can graph it.
 Solve for "y" from the second equation:
 
  You can identify that:
  
 
 Notice that the slopes and the y-intercepts of the first line and the second line are equal; this means that they are exactly the same line and the System of equations  has<u> Infinitely many solutions.</u>
 See the graph attached.
