S(x,y) = (5,1)

Question 11.
T(2, 5)
Answer:
The location of (2,5) is shown on the coordinate grid below.
The x-coordinate is 2.
The y-coordinate is 5.
To locate (2,5), move 2 units to the right on the x-axis and 5 units up on the y-axis.

Explanation:
The numbers on a coordinate grid are used to locate points.
Each point can be identified by an ordered pair of numbers;
that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate.
T(x,y) = (2,5)

Question 12.
U(0, 0)
