Slope is change in y over change in x.
Change in y=1.
Change in x=3.
Start at the given point (0,-2).
(3,-1) is also a point on the line.

First use the point-slope form of the equation of a line to derive an equation for the desired line:
 )
Where )
are the coordinates of the given point and 
is the given slope.
Once you have your equation, pick any value you like for 
except 0. That's because the point you were given has 0 as an coordinate and picking 0 won't tell you anything new. Substitute this value into the equation and do the arithmetic required to determine the value of 
that results. The ordered pair consisting of the value you chose and the value that resulted from that choice is a point on the line.
If you were given a series of choices that you just didn't bother to share, make your selection for be one of the coordinates given. Keep checking until you find one of them that results in the listed coordinate.
