How can you graph an equation? I don't get how an equation can be graphed.

If you are using excel have as many rows as you need labeled, highlight them all go to insert, then there will be a section called graphs, then chose which graph you need scatter, pie, line etc.

To graph an equation, start by drawing a pair of perpendicular lines and label each of them x and y. Draw a dot on the y axis to make it the y-intercept of the graph. Choose a value for x other than 0 and mark this on the x-axis you've drawn then lightly draw a vertical line that crosses this value of x on your x-axis. Solve for y then lightly draw a horizontal line that crosses this value of y on your y-axis. Once you draw a straight line between this dot and the y-intercept and extend it, it makes the graph of your equation.

You graph the equation by taking a number from the x-axis and plug it into the equation. When you solve the equation for y use the y number to plot the point on the graph. Do this until you have enough points to draw the equations graph
