The most common way to graph an equation in standard form is to find the x and y intercepts. The x and y intercepts are the two points where the line crosses the x and y axis. To find the intercepts, first set x equal to 0 and solve for y (this is called the y-intercept). Find a linear function whose graph has the given slope and y -intercept. 16).Slope. 7 4. , y-intercept (0, -5). 42). Find an equation of the line having the specified slope and containing the indicated point. Intercepts. The x-intercept is the point where the line crosses the x-axis.Example: 2 Find the x and y intercepts of the equation 3x 4y 12. Solution: To find the x-intercept, set y 0 and solve for x. With that information, you know that two points on the line at (5,0) and ( 0,8). Now you find the slope between those two points: (8-0)/(0-5) -8/5 Since slope is also -A/B, and an equation in standard form is Ax By C, you know the first part of the equation is 8 x 5y something. 4 marks) 2.

The following chart represents a few of the more useful methods1) Find an equation of the line with x-intercept 6 and y-intercept 3. 2x 3y-4 0 and x-5y 7 Here first we have to find the intersection point of these two lines. So on solving both equation simultaneously we have x 41/13 and y -10/13. Let the equation of straight line in intercept form is x/a y/b 1 Here a is x -intercept and b Finding intercepts of Linear Equations: An x-intercept is the x-coordinate of a point where a graph crosses the x-axis.Example: Find the x-intercept and y-intercept for the graph of the line. Solution Therefore, the x-intercept is (4, 0). To find the y-intercept, set x 0. Hence the y-intercept is (0, 6). Note that this linear equation is graphed above.Graphing Lines Using Intercepts. Since two points determine a line, we can use the x- and y-intercepts to graph linear equations. To find the y-intercepts of an equation, let x 0 then solve for y. In point notation, it is written as ( 0 , y ). y-intercept of a Line.Our solved values for both x and y intercepts match with the graphical solution.
