step 1

Graph the given points

(0, 5)

(0.5,5.7)

(1, 6.5)

(1.5,6.7)

(2,8.5)

(2.5,9.5)

using a graphing tool

see the attached figure

Find out the equation of the line that best represents this situation

we take the points

(0,5.0) and (2, 8.5)

Find out the slope

m=(8.5-5.0)/(2-0)

m=3.5/2

m=1.75

the equation of the line is

y=1.75x+5

therefore

For x=5.0 kg

substitute

y=1.75(5.0)+5

y=13.75 cm
