decide whether the given ordered pair is a solution of the equation:

1. 3y+12x=-4; (1/5, -35/15):

2. 8-3x+24y=0; (5, 23/24)

I think neither of them are.

_______

find the x-intercept of the graph of the equation.

3. 13x-24y=-5

--> x=-5/13

4. -14+6y=7x

--> x=-2

__

find the y-intercept 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
