Question

Line AB contains points A (1, 2) and B (−2, 6). The slope of line AB is___. A. Zero B. Undefined C. Positive D. Negative

Answer 1

Slope=6-2/-2-1=4/-3=-4/3 So the answer is D a negative number.

Answer 2

The slope:
m = Rise / Run = ( y 2 - y 1 )/ ( x 2 - x 1 ) = ( 6 - 2 ) / ( -2 - 1 ) = - 4/3
Answer: 
The slope is D ) Negative
