The line graphed represents the first of two equations in a system. If the 2nd equation in the system passes through

 $\left(-4,\ -1\right)$  and  $\left(3,\ 6\right),$  what would be the solution to the system? 

• The only solution to the system is  $\left(0,\ -1\right).$  

• The system would have infinitely many solutions. 

• The only solution to the system is  $\left(2,\ 1\right).\$  

• The system would have no solution.

Mrs. Mayberry is trying to decide between two nanny services. Nanny service #1 charges a flat transportation fee of $15 plus $20 per hour. Nanny service #2 charges a flat transportation fee of $5 plus $30 per hour. Write two equations (one for each nanny service) to represent the total charges, y, for x hours.

• $y=15x+20$
  $y=5x+30$
  

• $y=20x+15$
  $y=30x+5$

• $y=20x+5$
  $y=30x+15$
  

• $y=15x+30$
  $y=5x+20$
