Slope and Y-InterceptTickets to a concert cost 12$ teacher plus a 4$ processing feem=b=

Given :
Tickets to a concert cost 12$ each plus a 4$ processing fee
so, the slope = $12 ( the cost for each )
And the y - intercept = $4 ( will paid one time )
So, the answer is :
[tex]\begin{gathered} m=12 \\ b=4 \end{gathered}[/tex]
