Line them up!

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 y-intercept of the graph (the point at which the graph crosses the y-axis).

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

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 y-axis.

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

Draw a straight line between this dot and the y-intercept. Extend this line in both directions to the edges of your graph. This line is the graph of your equation.
