Example 1 Graph the equation of the line 2x4y=8 using its intercepts I hope you recognize that this is an equation of a line in Standard Form where both the x and y variables are found on one side of the equation opposite the constant term It is a common practice in an algebra class to ask students to graph the line using the intercept method when the line is in Standard Form Graph the equation \(y=\frac{2}{3}x1\) This equation is already in SlopeIntercept Form The slope is identified as m equals twothirds m=23 and the yintercept is at the ordered pair, (0, negative 1) (0,1) That is where the graphing begins Plot the first point at the yintercept, then move from that point according to the slopeIn this case xintercept doesn't exist since equation $x^22x2=0$ does not has the solutions (use quadratic equation solver to check ) So, in this case we will plot the graph using only two points So, in this case we will plot the graph using only two points

The yintercept is the point where the graph crosses the yaxis At this point, the xcoordinate is zero To determine the xintercept, we set y equal to zero and solve for x Similarly, to determine the yintercept, we set x equal to zero and solve for y For example, lets find the intercepts of the equation latexy=3x 1/latex In your example at the top of this page, you end up with the equation (#1), y= x^2x2 for the parabola but you rule it out because this equations leads to a y intercept of 2 whereas the graph shows a y intercept of 3 So far, so good You then go about solving a system of three equations to get the equation(#2) y = 15 x^2 15x 3The fourth equation is the familiar slopeintercept form;
