    Answer:

    y = -½x + 7

    Step-by-step explanation:

    Perpendicular lines have the product of their gradients equal to -1

    For this to be true, since the first gradient is 2, the second gradient must be -½

    So the first part is

    y = -½x + c

    We substitute our point to get c

    5 = -½(4) + c

    7 = c

    Our line is

    y = -½x + 7

    FYI slope-intercept form is y = mx + c
