Line a passes through (2, 10) and (4, 13). Line b passes through (4, 9) and (6, 12).

Line c passes through (2, 10) and (4, 9).

perpendicular to . The slopes are .

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
