11. Graph the set of data. Decide whether a linear model is reasonable. If so, draw a trend line and write its equation.

{(1, 7), (–2, 1), (3, 13), (–4, –3), (0, 5)}

A; y=0.9x+8.6
b; y=(2/5)x-2
c; y=(5/2)x+5
d; y=5

i checked and none are right welll to me

anonymous · Answer

it looks like the closest one is (5/2)x+5. remember that a model does not have to fit exactly a set of data, just the majority of it

oh. i didnt know that. i thought it had to be exact. thank you (:
