Answer 1

y=1.797 x + 0.904

Explanation:

y=1.797 x + 0.904

You could use line of best fit (least squares).

You can plot the provided equations & points, too.

B and C cannot be options; they have a negative slope. Just looking at the points, as x increases, y increases, so the slope is positive.

D most closely fits the data and would be the answer using least squares method.
