Question

1. in which quadrant does the point (2, -2) lie? 1st quadrant a 2nd quadrant b 3rd quadrant c 4th quadrant d 23. if (a, b) is a point that lies on the x - axis, what is the value of b? 24. plot the point (4, -8) on the coordinate plane. plot the point on the number plane.

Explanation:

Step1: Identify quadrant for (2, -2)

A point $(x,y)$ has $x>0, y<0$ in 4th quadrant.

Step2: Find $b$ for $P(a,b)$ on x-axis

All points on x-axis have $y=0$, so $b=0$.

Step3: Describe plotting (1, -8)

Move 1 right on x-axis, 8 down on y-axis.

Answer:

1. D. 4th quadrant
2. $0$
3. To plot $(1, -8)$: Locate $x=1$ on the horizontal x-axis, then move 8 units down along the vertical y-axis and mark the point at this position.
