The signs of a point's coordinates affect where the point is on a coordinate plane because an X-coordinate being negative or positive tells how far to the right or left of the Y-axis a point is. Vice versa, the Y-coordinate being positive or negative says how far above or below the X-axis a point is on a coordinate plane.
Each point will plot to only one place in the coordinate plane. So, I don't know what you mean by plotting anywhere and you'll get the same result. You won't
Since 5 is being multiplied with q dividing both sides by 5 would cancel out the 5 from 5q leaving us with q and on the other side of the equal sign 5/7 or 1.4 is going to be the value of q
