    Parallel lines have the same slope. So first, find out the slope of 2x + y = 8, by putting it in y = mx + b

    y=2x+8

    So the slope is 2 Now we're given the points (-2, 1) So slope = 2 Points = (-2, 1) Plug those into: y - y1 = m(x - x1) Where y1 and x1 are points and m is the slope

    So the equation is y-1=2x+4

    No put that in y = mx + b
