Use the point-slope form: y-k = m(x-h).
Here, y-[-1]) = (17/14)(x+6), or y+2 = (17/14)(x+6). This could, of course, be solved for y if you wish. Mult. both sides by 14, we get 14y+28=17(x+6).
This becomes 17x + 102 - 14y - 28 = 0, or 17x -14y + 74 = 0 (which is standard form). You could also write 17x - 14y = -74.
Assuming that the actual question reads lines b and c are perpendicular to line d
we are given that c is perpendicular to line d and parallel to line a. Since b is also perpendicular to line d, a b and c must all be parallel (draw it out will make a lot more sense)
So b is also parallel to line a
80 because if you multiply all them you would get 64,000 then divide it
The answer would be C. 3x + y = 5
