Question

Referring to the Fig. in Question #42, give the coordinates

of the point Y in the format (x,y).

Answer 1

(x, y) = (0, -3)

Explanation:

The point Y is on the y-axis. Its x-coordinate will be zero, since it is neither left nor right of the y-axis.

The point Y is 3 units below the x-axis, so its y-coordinate is -3. This is the value you can read on the y-axis next to point Y.

(x, y) = (0, -3)

_____

U(-5, 0)

V(-3, 3)

W(5, 5)

X(-4, -5)

Y(0, -3)

Z(2, -1)

It is a good idea to learn to read coordinates from a graph. You will be doing it a lot. The x-coordinate is the number of units right of the y-axis. The y-coordinate is the number of units up from the x-axis. Left or down makes the coordinate negative.
