Please help I don't get this at all-

So, to start off, the two places given are, (-5.5, 2) and (2, -5.5)

The first number is described in the x plane and the second number is described in the y plane.

Firstly, you would plot -5.5 in the x and 2 in the y and see where they meet up, this is located in Quadrant Q.

Secondly, you would plot 2 in the x and -5.5 in the y and see where they meet up, this is located in Quadrant S.

Question A) The starting point is in Quadrant Q and The ending point is in Quadrant S

Question B) Since the check point is located at (5.5, 2) (which is located in Quadrant P), the main difference is that you only have to move along the x axis which means that the y stays the same but the x changes

Hope that helped!

y = x + 95

y = 42 + 95

y=137 mm hg
