Given the scatter plot below, which of the following equations best models the data?

Rmember that the form y = mx + b is a straight line whose y-intercept is b and slope is m.

On the graph you can see that the y-intercept is beteween 0 and 5.

The equations given as options have y-intercepts 6, 20, 18, and 3, in that order.

And the only equation of the options that meet that is the option D. y = 3x + 3.

You can also check that the slope of that equation is 3 and it is roughly the slope of an intermediate line between the dots.

option D. y = 3x + 3.

I'm sure the answer is a
