    The answer is A

    -2x/-2 will cancel out and -20 / -2 is = to 10 so x-intercept is (10,0)

    if you rearrange the expression to y form...

    -2x - 4y = -20 ( add 2x to both sides)

    -4y = 2x - 20 ( divide by -4)

    y= -1/2x + 5

    the y intercept is 5 then you can tell the slope is -1/2, when you graph that slope starting at y-intercept and eventually you reach the x axis at (10,0)

    so your answer would be A

    -2x-4y=-20, divide by -2

    x+2y=10, subtract each side by 2y

    x=-2y+10

    This is in slope-intercept form (x=my+a, m=slope, a=x-intercept) so the x-intercept is 10

    A

    Simply remove the whole y-value out of the equation, leaving you with:

    -2x=-20

    Then solve!
