Question

in which quadrant does the point (-10, 9) lie?
quadrant i
quadrant ii
quadrant iii
quadrant iv

Explanation:

Step1: Recall quadrant rules

In the coordinate - plane, in Quadrant I, both \(x\) and \(y\) are positive (\(x>0,y > 0\)); in Quadrant II, \(x\) is negative and \(y\) is positive (\(x<0,y>0\)); in Quadrant III, both \(x\) and \(y\) are negative (\(x < 0,y<0\)); in Quadrant IV, \(x\) is positive and \(y\) is negative (\(x>0,y < 0\)).

Step2: Analyze the given point

For the point \((- 10,9)\), \(x=-10<0\) and \(y = 9>0\).

Answer:

B. Quadrant II
