A 41 slope travels 4 points up for every 1 point. The quadratic equation can be written in three different forms. This will be the line that represents the equation.
For example if the inequality is.
Construct a set of rectangular axes showing the scale and the variable repre- sented by each axis. To graph a linear equation all you have to do it substitute in the variables in this formula. And the general way of writing it is y is equal to mx plus b where m is the slope. If you know an equation is linear you can graph it by finding any two solutions x 1 y 1 and x 2 y 2 plotting these two points and drawing the line connecting them.
