A line that passes through (–1, –4) and (2, k) has a slope = k. What is the value of k?	Choose the correct choice from the following:
A) 3 / 4	B) 1	C) 4 / 3	D) 2	E) 7 / 2

Rationale: "slope = ( y 2 - y 1 ) / ( x 2 - x 1 ) = > k = ( k + 4 ) / ( 2 + 1 ) = > 3 k = k + 4 = > k = 2 ans d it is !"
Answer: D
