Write an equation to model this situation (use m for meters and s for seconds)

phi · Answer

you can think of the two pairs

13,2050
and
16,1900
as points.

and the problem is to write the equation of a line, given two points.

phi · Answer

to keep from being confused,  use (x,y) as normal,
and at the end, rename x as  s  and y as m

phi · Answer

to find the equation of a line, first find the slope:  change in y divided by change in x
can you do that ?
