Answer:

1.      In the equation: y = 2x + 2, the coefficient of the x term is the slope,

therefore the slope is 2. 

2.      On the graph, while x changes from 1 to 2, a difference of 1, the y value increases by 2,

      so the slope is 2/1 or 2.  

3.      For the table, each time x increases by 1, y increases by 2,

      so the slope is 2/1 or 2.
