If we are to observe closely the given equation above as,
y = 1/2x - 2
it is in the form of slope-intercept form. The general form of the equation of the line in its slope-intercept form is,
y = mx + b
where m is the slope and b is the y-intercept.
Hence, the equation can be graphed using the slope and the y-intercept. In this equation, the slope is 1/2 and the y-intercept is -2 such that the line passes through (0, -2).
