Question

HELP ASAP PLEASE!!!!!!!!!!!!!!!!!

Answer 1

`\huge\boxed{Hello\;there!}`

These are the equations that represent linear functions:

`\bigstar` x=y

`\bigstar` x=2y+4

Linear functions don't have an x² term.

The first function does have an x squared term, so it's not linear.

Therefore,

`\huge\boxed{\mathfrak{Answer:{\sf{Options\;B\;and\;D}}}}`

`\bold{Hope\;it\;helps!}`

Answer 2

second / fourth options

Explanation:

A linear function has both x and y to the power of 1

y = x² - 19 ( x raised to power 2 ) ← not linear

x = y ( both variables are raised to power of 1 ) ← linear

y = 3x² ( x raised to power of 2 ) ← not linear

x = 2y + 4 ( both variables raised to power of 1 ) ← linear

y = x(2x + 4), that is

y = 2x² + 4x ( one term has variable raised to power 2 , that is x² ) ← not linear
