1: When an equation has 2 variables, it is called a/an:
inequality
linear equation
coordinate system
2: How many solutions will an equation line x + y = 6 have?
2 6 an infinite number
3: Why do mathemeticians use the phrase ordered pair?
It is a pair of numbers always listed in the same order: (x, y).
The pair of numbers can be put in any order.
They like to order pairs.
4: Which of these solutions is written as an ordered pair?
{3, 2} (3, 2) 3, 2
5: The rectangular coordinate system consists of 2 number lines which . . .
are parallel, therefore never intersect.
intersect at acute angles.
intersect at right angles.
6: In a rectangular coordinate system, the horizontal line is the . . .
x axis. y axis. origin.
7: In a rectangular coordinate system, the vertical line is the . . .
x axis. y axis. origin.
8: To graph the ordered pair (3, 2), we first move 3 places . . .
upward. to the left. to the right.
9: To continue #8; we then move 2 places . . .
upward. to the left. to the right.
10: To graph the ordered pair (-3, -4), we first move 3 places . . .
downward. to the left. to the right.
11: To continue #10; we then move 4 places . . .
downward. to the left. to the right.
12: In figure 1 above, which point corresponds to the ordered pair (3, 0).
H B F
13: In figure 1 above, which point corresponds to the ordered pair (-1, 4).
G D E
14: In figure 1 above, which ordered pair corresponds to the point A?
(-4, -2) (4, 2) (-4, 2)
15: In figure 1 above, which ordered pair corresponds to the point J?
(-3, 4) (4, -3) (-3, -4)
