In which quadrant does the point (-18, 18) lie
well,
x is negative to the left of the y-axis
y is positive above the x-axis
so, which quadrant is that?
To determine the quadrant in which a point lies, you can look at its x-coordinate and y-coordinate.
In this case, the given point is (-18, 18). The x-coordinate is -18 and the y-coordinate is 18.
Since the x-coordinate is negative and the y-coordinate is positive, we can determine that the point (-18, 18) lies in the second quadrant.
To visually understand this, you can draw a coordinate plane with four quadrants, labeled I, II, III, and IV. The given point, (-18, 18), will be in the upper left region of the coordinate plane, which corresponds to the second quadrant.
