Are those multiple choice answers? Because I don't think it's either of those (although you can only estimate roughly from looking at the graph)

jdoe0001 · Answer

you're expected to look at the "best-fit line" in the graph and get the value when the tree is 50 inches high

anonymous · Answer

no @DebbieG

debbieg · Answer

ok, well, you do it like @jdoe0001  said - find the height=50 on the vertical axis, look ove to the line, and then see where you are on the horizontal axis. I could see it being close to 20 (I think more like 30), but I'm not sure where you would get 60 from ??

anonymous · Answer

im looking at the height @jdoe0001 which is 50
when I look across the age of 20 & 60 are on the line

debbieg · Answer

Oooh, I see what you are doing. You are looking at the plotted points. Those are the points USED to find the best-fit line. You are supposed to look at the LINE.

jdoe0001 · Answer

hmmm, you're not supposed to look at the dots, you're supposed to nevermind the dots and just use the line

debbieg · Answer

The line is computed from the points, so it has some equation

y=mx+b

You are basically being asked to estimate what x is, if y=50.
