Answer:
- The y-coordinate should be [tex]-3\frac{1}{2}[/tex]
Step-by-step explanation:
The red point is in the third quadrant where both x and y coordinates are negative.
The first number of an ordered pair is the x-coordinate, and the second number is the y-coordinate.
The point that Bernardette wrote [tex](-5,-4\frac{1}{2})[/tex] has x-coordinate -5 and y-coordinate [tex]-4\frac{1}{2}[/tex].
To find the x-coordinate of the red point, you go straight up, vertically up, until to you get the x-axys, then read the mark where you intercepted the axis. In this case it is -5. Hence, the x-coordinate of the point that Bernardette wrote is correct.
To find the y-coordinate of the red point, you move horizontally to the right until you get the y-axis. Then, read the mark. In this case it is halfway between -3 and -4. That is [tex]-3\frac{1}{2}[/tex] . Hence, the correct choice is the last one: The y-coordinate should be [tex]-3\frac{1}{2}[/tex].
