What is the value of the x-coordinate of point w? enter your answer as a decimal to the nearest 0.5.

I attached a screenshot with the complete question.

x-coordinate of point w is nearly -3.5

Explanation:
To get the x-coordinate of a certain point, we would need to read the value of this point on the horizontal axis (the x-axis).
Taking a look at point w, we would find that it is in the second quadrant. This means that it has a negative x-value.
Now, reading the x-value on the horizontal axis, we can see that it is nearly midway between points -3 and -4.
This means that point w is approximately -3.5

Hope this helps :)
