What is the slope of the line of best-fit in the scatterplot below? On a graph, a trend line goes through points (3, 12) and (6, 19). StartFraction 9 Over 27 EndFraction StartFraction 3 Over 7 EndFraction StartFraction 7 Over 3 EndFraction StartFraction 27 Over 9 EndFraction

To find the slope(m), use the slope formula:

    And plug in the two points.

(3, 12) = (x₁, y₁)

(6, 19) = (x₂, y₂)

[lines go from left to right, so the point furthest to the left is your 1st point]

     Your answer is the 3rd option
