Question

Find the y-coordinate to each given pair.y = 6x-15, for (8, ) (-1, ) (5, ).

Answer 1

The given expression is

`y=6x-15`

We need to find y-coordinates for, x=8, x=-1, and x=5.

Let's replace each case to get each y-coordinate.

For x=8

`y=6(8)-15=48-15=33`

For x=-1

`y=6(-1)-15=-6-15=-21`

For x=5

`y=6(5)-15=30-15=15`

Therefore, the complete ordered pairs are

`(8,33),(-1,-21),(5,15)`
