Question

ME AJUDEM POR FAVOR É MUITO URGENTE classifique as retas ''r'' e ''s'' conforme suas propriedades relativas:

Answer 1

$b) \\ (r)\mapsto-y=-x+3~~~\times(-1) \\ (r)\mapsto y=x-3 \\ \\ (s)\mapsto-2y=-2x-3~~\times(-1) \\(s)\mapsto 2y=2x+3 \\(s)\mapsto y= \frac{2x}{2} + \frac{3}{2} \\ \\ (s)\mapsto x+ \frac{3}{2} \\ \\ como~~mr=ms~~s\tilde{a}o~~paralelas$

$c) \\ (r)\mapsto 2y=-x+5 \\ (r)\mapsto y=- \frac{x}{2} + \frac{5}{2} \\ \\ (s)\mapsto2y=-x+5 \\ (s)\mapsto y= -\frac{x}{2} + \frac{5}{2} \\ \\ mr=ms~~~e ~~nr=ns~~~~ coincidentes$ 


$d) \\ (r)\mapsto 3y=3x+3 \\ (r)\mapsto y= \frac{3x}{3} + \frac{3}{3} \\ \\ (r)\mapsto y= x+1 \\ \\ (s)\mapsto 3y=3x+1 \\ (s)\mapsto y=x+ \frac{1}{3} \\ \\ mr=ms~~~paralelas$
