Answer:

Step-by-step explanation:

A) The formula x =  -b ± sqrt(b2 - 4ac)/2a calculates the roots of a quadratic equation.

D) The formula M = ((x1 + x2)/2, (y1 + y2)/2) calculates the mid-point of the line joining the points  and .

B) The formula m = ((y2 - y1)/(x2 - x1)) calculates the slope of a line.

Hence, option B should be used to find the slope of EF.
