What is the slope of (0, 0) and (-1/2,1/3)?

Question

I know the m slope formula but haven't done these in a while. Mainly having trouble with the fractions.

Answer 1

Slope of the line is given by m = (y2 - y2)/(x2 - x1)
= (1/3 - 0)/(-1/2-0)
= (1/3) / (-1/2)
= -2/3

Answer 2

Let the points are (x₁, y₁) = (0, 0) and (x₂, y₂) = (-1/2, 1/3).

Slope (m) = [(y₂ - y₁)/(x₂ -x₁)]

m = (1/3 - 0)/(- 1/2 - 0)

m  = (1/3) / (- 1/2)

⇒ Slope,m = -2/3.
