## Algebra: A Combined Approach (4th Edition)

a. $(2, 3)$ b. $(-1, 5)$ c. $(-3, -2)$ d. $(3, -1)$ e. $(5, 0)$ f. $(0, -3)$
a. Quadrant 1 is where both x-coordinate and y-coordinate of a point are positive values. b. Quadrant 2 is where the x-coordinate is a negative value and y-coordinate of a point is a positive value. c. Quadrant 3 is where both x-coordinate and y-coordinate of a point are negative values. d. Quadrant 4 is where the x-coordinate is a positive value and y-coordinate of a point is a negative value. e. When a point is on the x axis, it lies on the line $y=0$, so the y-coordinate must be 0. f. When a point is on the y axis, it lies on the line $x=0$, so the x-coordinate must be 0.
