Mar 9, 2017 · How do you graph the equation y = − 2x? Method 1: Draw a line connecting the points extending it to the edge of the graph paper. You may use a minimum of two values but I would suggest 3. If all three do not sit on the line then your maths is wrong somewhere. Method 2:

To graph the equation y = − 2 x, choose points by substituting values for x to find y values, such as (0, 0) and (1, -2). Plot these points on the coordinate plane and connect them with a straight line. The line will have a slope of − 2 and crosses the origin.
