Question

If the ordinate is three more than twice the abscissa and x {-1, 0, -}, which of the following sets of ordered pairs satisfies the given conditions? {(-1, 1), (0, 3), (-, )} {(-1, 1), (0, 3), (-, )} {(-1, -1), (0, 3), (-, 1)}

Answer 1

Answer:The abscissa is the x-coordinate of the ordered pair and the ordinate is the y-coordinate. The ordered pair is therefore given to be,

(abscissa, ordinate)

or (x , y)

From the given, it is stated that the ordinate is three more than twice the abscissa. The ordered pair can therefore be written as,

(x, 2x + 3)

If x = -1 then,

y = 2(-1) + 3 = 1

Ordered pair : (-1, 1)

If x = 0

y = 2(0) + 3 = 3

Ordered pair : (0, 3)

Hence, the answer to this is either the first choice or the second choice which appears to be just the same.

Answer 2

The abscissa is the x-coordinate of the ordered pair and the ordinate is the y-coordinate. The ordered pair is therefore given to be,
(abscissa, ordinate)
or (x , y)

From the given, it is stated that the ordinate is three more than twice the abscissa. The ordered pair can therefore be written as,

(x, 2x + 3)

If x = -1 then,
y = 2(-1) + 3 = 1
Ordered pair : (-1, 1)

If x = 0
y = 2(0) + 3 = 3
Ordered pair : (0, 3)

Hence, the answer to this is either the first choice or the second choice which appears to be just the same.
