(1,2)and(3,1) is it a parallel, perpendicular ,or neither

The lines are neither parallel nor perpendicular.

Step-by-step explanation:

Slope of line through (1,2) and (3,1) = (1-2)/(3-1) = -½

Slope of line through (0,-1) and (2,0) = (0-(-1))/(2-0) = ½

The slopes are not the same, so the lines are not parallel.

The product of the slopes is not -1, so the lines are not perpendicular.
