    x=5/4y-2 x+2=5/4y 5/4y = x+2 y = 4/5x + 2(4/5) y = 4/5x + 8/5

    the slope of y = 4/5x + 8/5 is 4/5 so the slope of x=5/4y-2 is also 4/5

    the perpendicular slope would be -5/4 because you flip the fraction and the sign of 4/5

    so your answer will have a slope of -5/4 not -4/5

    the original slope was 5/4 not 4/5

    you first need to solve for y to get the slope

    5/4 is not the original slope
