A. y=14/45x
B. y=45x+15
C. y=45/14x

Answer:

The correct option is C.

Explanation:

If a line passing through two point then the equation of line is


y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

From the given graph it is clear that the line of best fit passing through the points (0,0) and (14,45). So, the equation of line of best fit is


y-0=(45-0)/(14-0)(x-0)


y=(45)/(14)x

The equation of line of best fit is
y=(45)/(14)x, therefore the correct option is C.
