(Assume the bottom and left legs are the x- and y-axes respectively)
The equation of the line can be written in point-slope form:


We wish to find the x- and y-intercepts. Therefore we set y to zero and solve for x, then set x to zero and solve for y. The x-intercept is

and the y-intercept is



Multiply these two and divide by 2 to find the area.
