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?

use the slope formula to find slope

slope(aka m) = (y1-y2)/(x1-x2)

find the slope for both.

If slopes are the same, then the lines are parallel
If one slope is the exact negetive reciprocal , then the lines are perpendicular

if both slopes don't show either relationship, then "neither" is your answer

(a million) A line consists of the criteria (a million,-3) and (a million, -2) is the line x = a million (parallel to the y-axis.) (2) A line consists of the criteria (a million,-3) and (a million, -2) has the slope ok = [(-3) - (0)] / [(-3) - (-2)] = 3 Then its equation is y = 3x + m. utilizing the point (-2,0), we've 0 = 3(-2) + m or m = 6 hence, line (2) has the equation y = 3x + 6. answer: those lines (a million) and (2) are neither parallel nor perpendicular. reliable success!
