Slope of a Line

What is the slope in the following equations?

1. $y=4x+2$
2. $y=-3x-1$
3. $y=\dfrac{1}{2}x+7$
4. $2y=4x+12$
5. $6x-y=5$
6. $-3y-7=2x$

Find the slope of the line that passes through the following two points:

7. (3,4) and (8,9)
8. (-2,3) and (-4,7)
9. (-6,-2) and (1,1)
10. (1,2) and (-3, -4)
11. (9,2) and the origin
12. (3,3) and (3,7)
