A line contains the points (3, -1) and (-1, 2). Another line graphed in the same coordinate plane contains the points (2,0) and (-2,3). Based on the slope of these lines, are they parallel, perpendicular or neither?
they r parallel becoz they hav the same slope which is 3/-4
Calculate the slope of the lines. If they are parallel, they will have the same slope. If they are perpendicular, the slopes will be inverses of each other (for example, -2 and 1/2 are perpendicular slopes). In other words, if you multiply the slopes together and get -1, they are perpendicular.
