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)
