Answer:

The answer is B

Statement: slope of DF = slope of BC

Reason: Transitive Property of Equality

Step-by-step explanation:

∵ He find the slope of BC from point B and point C

∵ He find the slope of DF from the mid-point of AB ad the mid-point of

   AC

∵ The two answers are equal

∴ The two slopes are equal

∴ Statement is slope of DF = slope of BC

∴ Reason is transitive property of equality

Answer:b
