    Choose the equation of a line in standard form that satisfies the given conditions. perpendicular to 4x + y = 8 through (4, 3).

    Step 1: Find the slope of the line 4x + y = 8.
    In y = mx + b form, we have y = -4x + 8.

    The slope is -4.

    To be perpendicular to a line, the slope must be a negative reciprocal of the line it intersects with.
    Reciprocal of -4 = -1/4
    Negative of this = -1(-1/4) = 1/4

    Using our slope calculator, we get y = 1/4x + 2
