    no solutions

    Step-by-step explanation:

    y = - 10x + 5

    y = - 10x - 9/7

    They are both equal to y so set them equal to each other

    -10x + 5 = - 10x - 9/7

    Add 10x to each side

    -10x + 5 + 10x = - 10x - 9/7+10x

    5 = - 9/7

    This is never true so there are no solutions
