the equation is
[tex]C(s)=150s+4500[/tex]the vertical axis is C and the horizontal is s
now
we can calculate two numbers, join with a infinite line and that is it
s=0
[tex]\begin{gathered} C(0)=150(0)+4500 \\ C(0)=4500 \\ \end{gathered}[/tex]s=10
[tex]\begin{gathered} C(10)=150(10)+4500 \\ C(10)=1500+4500 \\ C(10)=6000 \end{gathered}[/tex]then place the points(0,4500);(10,6000) and join
