QUICK Which set of ordered pairs represents a function?
O {(8, –5), (1,0), (1, –5), (-5,6)}
O {(9, –4), (5,4), (9, -6), (4, –7)}
O {(7,-8),(-2,-6),(-1, -1), (-5, -1)}
O {(-3, -3), (8,6), (8, 7), (1,8)}

3rd option (7.-8),(-2,-6),(-1,-1),(-5,-1)

Step-by-step explanation:

A function is an input which has only one output (x,y)

1st option has 2 pairs which have 1 as x, so we can cross that one out.

2nd option has 2 pairs that have 9 as x

4th option has 2 pairs which have 8 as x

Which leaves you with the 3rd option as the only correct answer.

examine the two-step equation.

−  

7

4

+  

x

4

= 2

which property of operations allows you to add the same constant term to both sides?

multiplication property of equality

division property of equality

addition property of equality

subtraction property of equality
