    Answer:

    2y – x = 8  

    Step-by-step explanation:

    First get the slope of the line given

    y=-2x+5

    From the line, slope m = -2

    The slope of the required line M = -1/-2 = 1/2

    Substitute the point (-4, 2) and m = 1/2 into the point slope equation;

    y – y0 = m(x-x0)

    y – 2 = 1/2(x+4)

    2(y-2) = x+ 4

    2y – 4  = x+4

    2y – x = 4+4

    2y – x = 8

    Hence the equation of this perpendicular line is 2y – x = 8
