Question

Line a passes through the points (10, 4) and (1, 9). Line b passes through the points (7, 10) and (2, 1). Are lines a and b parallel, perpendicular, or neither?

perpendicular

beacause if a line passes through the point 7 so that answer is parallel but if we passes through the point 2,1 so the answer is perpendicular..
