Question

The scatter plot below shows the relationship between the length (x), in meters, and mass f(x), in kg, of a marine animal:

ordered pairs 1, 1 and 2, 11 and 3, 21 and 4, 31 and 5, 41 and 6, 52 and 7, 65 and 8, 71 and 9, 82 and 10, 94

Which of the following functions is best represented by the scatter plot?

f(x) = 9 − 10.3x
f(x) = −10.3 + 9x
f(x) = −9 + 10.3x
f(x) = 10.3 − 9x
