determine if each pair of lines is perpendicular, parallel, or neither. line 1: passes through (1,0) and (7,4) and line 2: passes through (7,0) and (3,6)
They are perpendicular (the slope of the first line is 2/3, and the slope of the second line is -3/2, which are reciprocals of each other, meaning they are perpendicular)
