Draw a pair of perpendicular lines. These are your axes (the plural of "axis"). Label the horizontal axis "x" and the vertical axis "y." Label several different values, both positive and negative, of x and y on both axes. This is the scale of the graph.

Remember that your equation should be in the form y = mx + b (if it is in a different form, solve for y in terms of x).

Draw a dot on the y axis at y = b. This is the yintercept of the graph (the point at which the graph crosses the yaxis).

Choose a value for x other than 0 and mark this on the xaxis you've drawn. Lightly draw a vertical line that crosses this value of x on your xaxis.

Plug the x value you chose into your equation.

Solve for y. Lightly draw a horizontal line that crosses this value of y on your yaxis.

Make a dot where the two lines you just drew intersect.

Draw a straight line between this dot and the yintercept. Extend this line in both directions to the edges of your graph. This line is the graph of your equation.
Tips & Warnings
 The value "m" in y = mx + b is the slope of the graph. The slope is the ratio of vertical change to horizontal change between two points on the graph.
 Example: The graph of the equation y = 2x + 5 has a slope of 2 and crosses the yaxis at y = 5.
