Question

Line QR contains (2, 8) and (3, 10) Line ST contains points (0, 6) and (−2, 2). Lines QR and ST are

Answer 1

Line QR :
(2,8)(3,10)
slope = (10 - 8) / (3 - 2) = 2/1 = 2
y = mx + b
8 = 2(2) + b
8 = 4 + b
8 - 4 = b
4 = b
and ur y int = 4

Line ST :
(0,6)(-2,2)
slope = (2 - 6) / (-2 - 0) = -4 / -2 = 2
and ur y int (0,6) = 6

same slopes. different y intercepts.....means Line QR and Line ST are
PARALLEL LINES
