Which of the following functions best models the data shown in the scatterplot below? y=3x+5y=x2+10y=x+8y=2x+

Given:
a graph is given
Required:
To simplify which option is correct
Explanation:
From the graph we know the model should be line. And it passes through (15,60)
if the model is y=x+8 , y =15+8=23
there is too much difference between 23 and 60, so y=x+8 is wrong
and y=3x+5 is right
Required answer:
y=3x+5
