    y=mx+b is slope intercept form where `m` is slope and `b` is y-intercept

    y=mx+b is slope intercept parallel lines should have the same slope example if the slope of line `a` is 2 then slope of line `b` would be 2 as wll slope of perpendicular lines are `negative reciprocal` if slope of line a is a/b then slope of `b` would be -b/a

    so part C) find the equation m=2 we already know that so y =mx+b use the order pair they gave u for x and y values and replace m with 2 to find b
