Which sets of ordered pairs show equivalent ratios? Use the grid to help you.
Check ALL that apply.

1.) (1, 2), (2, 3), (4, 7)
2.) (2, 2), (4, 4), (6, 6)
3.) (3, 1), (4, 1), (5, 1)
4.) (4, 1), (8, 2), (12, 3)
5.) (2, 1), (4, 3), (5, 4)

2, 4

Step-by-step explanation:

In 2, (2,2) has the same number on both sides, same with (4,4) and (6,6).

Therefore, it is equivalent.

In 4, dividing the first number by the second always results in 4. (4/1=4, 8/2=4, 12/3=4).

Therefore, it works.

The pattern used in 4 is how ratios work. Multiplying/dividing to get one consistent number.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
