Explanation:

Which is linear

A linear function is represented as any of:

`y = mx + b`

`y - y_1= m(x - x_1)`

`(a)\ 8x - 3y = 2`

Rewrite as:

`- 3y = -8x+2`

Divide by -3

`y = (8)/(3)x - (2)/(3)` -- by comparison to
`y = mx + b`, this is linear

`(b)\ y = |x - 4|-7`

This is an absolute function. It is not linear

`(c)\ y + 8=5(x - 4)`

By comparison to
`y - y_1= m(x - x_1)`, this is linear

`(d)\ y = -7`

by comparison to
`y = mx + b`, this is linear because
`m= 0`

Others are not linear
