y = mx + b
Slope is m, where mx is slope multiplied on the x, b is the y intercept, and y is the answer.
The line of best fit STARTS on 1, so we already knnow ther is going to be a "+ 1" at the end of the equation. Then, we count from the y intercept 1, all the way to a point that is touching the line of best fit. Remember, [tex]\frac{rise}{run}[/tex] which means you count how high to get from 1 to the data point, then count how far away horizontally to get to the data point.
Therefore, your answer would be y = 7/5x + 1.
Third choice, C.
