Finding x and y intercepts

Standard Form Ax + By = C x – intercept is when the y value is zero y – intercept is when the x value is zero

Example: -2x + 6y = 24To find the x-intercept cover y and solve for

x -2x = 24 therefore intercept is (-

12,0)To find the y-intercept cover x and solve for

y6y = 24 therefore intercept is (0,4)

Line intersects the axis at (-12,0) and (0,4)
