# find the x-intercepts and y-intercepts of the graph of the equation

Finding x-intercepts and y-intercepts. The intercepts of a graph are points at which the graph crosses the axes.We can confirm that our results make sense by observing a graph of the equation as in Figure 10. Notice that the graph crosses the axes where we predicted it would. STANDARD FORM The x- and y-intercepts are easy to find when an equation is in STANDARD FORM. The standard form of a linear equation is: Notes: A B are NOT BOTH zero (either A or B canDraw a line through the points. Example 2: Graph the equation 8x 4y -16 using intercepts. If you look at the graph of any function where both x and y intercepts exist, you will notice that the y coordinate is always zero for the x intercept and theTo find the x-intercept(s) of a function, solve for every x-value that satisfies the equation f(x) 0. In other words, to find the x-intercept(s) of a Find an equation of the line with slope m that passes through the given point. Put the answer in slope- intercept.Graph the function. 30) f(x) 4x. Find the value of the expression. 31). Graph each equation using the slope and y-intercept.10. Standardized Test Practice Which of the following is the x-intercept for. For simplicitys sake, this article will focus on the slope-intercept equation y mx b instead of theBefore you can find the equation, make sure you have a clear idea of what youre trying to find.A "system" consists of at least two different equations (and thus at least two lines on a graph). The straight line on the graph below intercepts the two coordinate axes. The point where the line crosses the x-axis is called the [x-intercept].We can use the characteristics of intercepts to quickly calculate them from the equation of a line. Just see how easy it is, as we find the x- and The graph also crosses the y-axis at the point (0, 2). This point is called the y-intercept.

To find the x-intercept, let y 0. (Any point on the x-axis has y-coordinate 0).For any equation of the form y mx b, the y-intercept is (0, b). Using the X and Y Intercept to Graph Linear Equations. Youve learned one way to graph aGraph the equation.
