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)}
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.
