You can create and solve a proportion to get this answer.
Let x be the number of litters in 2500.
1. Write out proportion. 1/1000=x/2500
2. Cross Multiply. 1000x=2500
3. Divide by 1000 on each side. x=25
how many solutions do intersecting lines have? - 0,1 or infinitely many
how many solutions do parallel lines have? - 0 or infinitely many
if you are looking at a graph and trying to find a solution what are you looking for? - for the point(s) when the graphs intersect
