Answer:
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.
