Answer:
Slope:
y-intercept: 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
The slope can be found with the following formula:

In this case you can say that:

Knowing this values you can substitute them into the formula and then evaluate, in order to find the slope. This is:

By definition, the line intersects the y-axis when the value of "x" is 0.
Notice in the table that when
, 
Therefore, the y-intercept is:
