Ava placed the point of her pencil on the origin of a regular coordinate plane. She marked a point after moving her pencil 4 units to the left and 7 units up. Which ordered pair identifies where Ava marked her point?

So, Let's solve this question by using cartesian plane.

  • Here, Origin is shown by (0, 0)
  • Ava moves 4 units left from origin. On the left side of origin, negative x axis begins. So, she reached (-4, 0) now.
  • Then, from that point she moved 7 units upwards. On the upper side, there is positive y axis. So, Finally she will reach point (-4, 7).
  • (-4, 7) is the coordinate of point which is 4 units left from y axis and 7 units up from x axis.
  • It lies on the second quadrant.

Well, What is cartesian plane?

A - A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a set of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.
