Answer:
Option A
Explanations:
The slope - intercept form of the equation of a line is:
y = mx + c
where m is the slope
c is the y-intercept
If a line of best fit is drawn on the on each of the scatterplots, only in the first scatterplot can the line of best fit intesect the y-axis at 2. A slope of 1/2 is also only possible when a line of best fit is drawn on the first scatterplot.
That is, c = 2
m = 1/2
Therefore, only the first scatterplot would have the line of best fit represented by the equation y = 1/2 x + 2
