answer: 2 1/2 (A)
if you look at the x and y numbers, options B-D are way too high for the chart.

Answer:

A.

Step-by-step explanation:

subtract two y points and the corresponding x points

so if you choose to subtract 20 and 15, you get 5

then you would subtract 4 and 2, you would get 2

put them in y/x fraction: 5/2

this simplifies to 2 1/2
