Answer:
a) Yes, the relationship is proportional.
b) [tex]y=25x[/tex], slope is 25
c) 350 miles
Step-by-step explanation:
a) Proportional relationships are linear functions that pass through the origin.
b) Proportional relationships can be written as [tex]y=kx[/tex], where [tex]k[/tex] is a constant of proportionality. Substitute any point the line passes through to find this constant.
c) Substituting [tex]x=14[/tex] into our function:
[tex]y=25x,\\y=25\cdot 14,\\y=\boxed{350}[/tex]
