    x intercept=-b/a

    y intercept=b

    Step-by-step explanation:

    to find x intercept put y=0

    0=ax+b

    ax=-b

    x=-b/a

    to find y intercept put x=0

    y=b

    -b/a = x

    Step-by-step explanation:

    To find the x intercept, let y = 0 and solve for x

    0 = ax+b

    Subtract b from each side

    -b = ax+b-b

    -b = ax

    Divide each side by a

    -b/a = ax/a

    -b/a = x
