Find the x- and y- intercepts for each equations. What is the x- and y- intercepts?
y= -2x + 8

  • Geometry -

    The x-intercept is the value of x when y=0.
    Thus, x-intercept is obtained by solving:
    0=-2x+8, or x=4

    Similarly, the y-intercept can be obtained from
    y=-2(0)+8, or y=8
    So the intercepts are (4,0),(0,8).
    The equation can also be written in the intercept form:
    x/4 + y/8 = 1
