Question 1174247
Question B indicates linear relationship.

Original points  (2014,100), and (2018,200).
Adjusted for 0 time is for year 2014, points are (0,100) and (4,200).


SLOPE:  {{{(200-100)/(4-0)=100/4=25}}}


EQUATION:   {{{y=25x+b}}}
{{{b=y-25x}}}
{{{b=100}}}
-
{{{highlight(y=25x+100)}}}



The description indicated an equation; not an inequality.


Year 2019 would correspond to x=5.
{{{y=25*5+100}}}
