Graphing Using x & y Intercepts
Algebra Honors

Finding the x & y intercepts.
Write the equation in standard form first Ax + By = C

To find the x – intercept ~ where the graph crosses the x-axis ~
2 Methods: Pick one. 1st Method: Cover up the y term and solve for x. 2x + 3y = 6 2x = 6 x = 3 2nd Method: Plug in 0 for y and solve for x. 2x + 3(0) = 6

To find the y – intercept ~ where the graph crosses the y-axis ~
2 Methods: Pick one. 1st Method: Cover up the x term and solve for y. 2x + 3y = 6 3y = 6 y = 2 2nd Method: Plug in 0 for x and solve for y. 2(0) + 3y = 6

Graph using X & Y intercepts.
2x + 5y = 10 (5, 0)x-intercept (0, 2)y-intercept

Graph using X & Y intercepts.
8x + y = 4 (1/2, 0)x-intercept (0, 4)y-intercept

Graph using X & Y intercepts.
3x + 4y = 24 (8, 0)x-intercept (0, 6)y-intercept

Graph using X & Y intercepts.
3x + 2y = 6 (2, 0)x-intercept (0, 3)y-intercept

Graph using X & Y intercepts.
4x - 3y = 12 (3, 0)x-intercept (0,-4)y-intercept

Graph using X & Y intercepts.
X = 5 (5,0) x-intercept NO y-intercept

Graph using X & Y intercepts.
4x - 5y = 10 (5/2, 0)x-intercept (0,-2)y-intercept

Graph using X & Y intercepts.
x - 2y = 4 (4,0) x-intercept (0,-2)y-intercept

Graph using X & Y intercepts.
y = 7 NO x-intercept (0,7)y-intercept
