List five ordered pairs for the function y = 2x – 1.

Set the x value to be -2, -1, 0, 1, and 2.

If x is -2, y is -5.

2 (-2) - 1 = -5

The coordinate pair would be (-2, -5).

If x is -1, y is -3.

2 (-1) - 1 = -3

The coordinate pair would be (-1, -3).

If x is 0, y is -1.

2 (0) - 1 = -1

The coordinate pair would be (0, -1).

If x is 1, y is 1.

2 (1) - 1 = -1

The coordinate pair would be (1, 1).

If x is 2, y is 3.

2 (2) - 1 = 3

The coordinate pair would be (2, 3).

Five ordered pairs could be (-2,-5), (-1,-3), (0,-1), (1,1), and (2,3).

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
