decide whether the given ordered pair is a solution of the equation:
1. 3y+12x=4; (1/5, 35/15):
2. 83x+24y=0; (5, 23/24)
I think neither of them are.
_______
find the xintercept of the graph of the equation.
3. 13x24y=5
> x=5/13
4. 14+6y=7x
> x=2
__
find the yintercept of the graph of the equation:
5. 17x+4y+10=0
> y= 2 1/2
6. 19+5y=15x
> y= 2 3/5
___
find the slope of the line passing through the points:
7. (5,5), (7,6)
> 11/3
8. (7,12), (4,13)
> 25/3
please check these and tell me whats wrong. thanks

I think 6, 7, and 8 need work.
