Line AB passes through the points A(-1, -2) and B(3, 8) Would AB be parallel to a line whose slope is equal to 3? Justify your answer.

Respuesta :

Answer:

Not parallel.

Step-by-step explanation:

It would be parallel if its slope is also 3.

Calculate slope of line AB = y2 - y1 / x2 - x1

8 - (-2) / 3 - (-1) =

8 + 2 / 3 + 1 = 10/4 = 2.5

2.5 =/= 3, it wouldn't be parallel.
