The line would have the form 2x+4y = c for some particular constant c.
c = 2*8 + 4*(-2) = 16 - 8 = 8.
Therefore the line is 2x+4y = 8, or x + 2y = 4.

Slope is 2.

Any line perpendicular to the given line must have slope . Such a line to pass through (8,-2), using the point-slope equation form, will be . Do what you need or want from this form.
