    Change the given equation to slope intercept form, y=mx+b That will help you determine the slope of the given line

    close 2y = 4x + 8 No divide everything by 2 so you get y= mx+b

    You'll see that the slope of the given line is 2. To have a perpendicular line, the slope is the opposite reciprocal.....-1/2

    Using the slope intercept formula and the point given (8,2) plug in and find b.

    2=-1/2(8)+b

    2=-4+b 6=b Now you can give the equation of a line perpendicular to the given line at the point (8,2). y=-1/2x+6
