    To find an x intercept you substitute 0 for Y and solve so

    4x (0) + 2 (0) = 9 (plug in)

    4x=9 (simplify)

    4x/4=9/4 (divide by four)

    your x intercept is 2.25 (2 1/4)

    You can double check by plugging your new x value into your simplified equation. (4x=9)

    4 (2.25) = 9

    9=9
