First, we have to find the slope with the formula below.


m=(y_2-y_1)/(x_2-x_1)

Let's replace the points (0, -1) and (2, 0).


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

Once we have the slope, we use the slope-intercept formula to find the equation.


y=mx+b

Where m = 1/2, and b = -1.


y=(1)/(2)x-1

Hence, the answer is the third choice.
