Respuesta :

if you substitute the x for 3, and multiply 4 times 3, you’ll get 12 and then you subtract 9 from 12 and then you’ll get 3. i’m pretty sure y=3

Answer with explanation:

The given equation of line is :

  y = 4 x -9

We have to find to value of , y when , x=3.

Substituting the value of , x=3 , in above equation

⇒y = 4 × 3 -9

y=12 -9

y=3

So, when, x=3,we get , y=3.
