Graph y=1/2x-3

Identify the equation as a linear function in slope-intercept form, which is y=m*x+b

Determine the y-intercept from the constant term b=−3 which corresponds to the point (0,−3)

Identify the slope m=1/2 which represents the "rise over run" (up 1 unit for every 2 units to the right).

Plot the y-intercept at (0,−3) on the coordinate plane.

Find a second point by starting at (0,−3) and applying the slope: move up 1 unit and right 2 units to reach the point (2,−2)

Draw a straight line passing through both points (0,−3) and (2,−2) to complete the graph.
