Please explain what the answer is step by step.

2,4,5

Step-by-step explanation:

The straight line has representation:

y=kx+n, where k and n are real numbers. We dont have ^2 or any other operation.

So:

1. Is not line because yx=9x-1

2. X=16+3y we can write like y=1/3X-16/3 so it is straight line TRUE

3. Ve have ^2 it is not staight line

4.8x-5y=30 is y=8/5x-6 it is line TRUE

5.y=-6(x+10)=-6x-60 it is line TRUE

6. Y=x(3-x)+1=3x-x^2+1 so we have ^2 it is not straight line.

Step-by-step explanation:

hello :

x=16+3y

8x-5y=30

y=-6(x+10)

hope this .
