    The general equation of the slope intercept form is y = mx + b. The first step is to subtract the whole equation by 5x. This leaves 4y on the left side. Then, divide the whole equation by 4, which results to option D. y = - 5/4x + 5/2

    5x + 4y = 10

    - 5x - 5x

    4y = - 5x + 10

    4 4

    y = - 1¹/₄x + 2¹/₂

    The answer is D.
