Respuesta :

#1

Constant of proportionality means slope

[tex]\\ \rm\rightarrowtail m=\dfrac{225-100}{18-8}=\dfrac{25}{2}[/tex]

#2

We need equation

[tex]\\ \rm\rightarrowtail y-100=25/2(x-8)[/tex]

[tex]\\ \rm\rightarrowtail 2y=25x[/tex]

Put x=1

[tex]\\ \rm\rightarrowtail 2y=25[/tex]

[tex]\\ \rm\rightarrowtail y=25/2=12.5[/tex]
