Answer:
The approximate equation of this line of best fit in slope-intercept form is .
Step-by-step explanation:
The point slope form of a line is
Where, m is slope and b is y intercept.
If a line passing through two points then the slope of the line is
It is given that the straight line of best fit joins the ordered pairs (0, 15) and (10, 0). So, the y-intercept is 15 and the slope of the line is
The y-intercept is 15 and the slope of the line is , therefore the approximate equation of this line of best fit in slope-intercept form is
