Option B: is the line of best fit in slope - intercept form
Explanation:
It is given that the straight line joins the ordered pairs and
We need to determine the line of best fit in slope - intercept form.
The equation of the line of best fit in slope - intercept form is given by
where m is the slope and b is the y - intercept
The slope can be determined by substituting the points and
in the formula,
Thus, the slope is
The y - intercept is the value of y when the value of the x - coordinate is zero.
Thus, from the ordered pair , the y -intercept of the graph is
Substituting the slope and the y - intercept in the equation , we get,
Thus, the equation of line of best fit in slope - intercept form is
Hence, Option B is the correct answer.
