Answer:
parallel : y = -3x + 3
perpendicular : y = 1/3x + 3
Step-by-step explanation:
rewrite 3x + y - 3 = 0
y = -3x + 3
parallel has the same slope
so
parallel : y = -3x + 3
perpendicular is negative reciprocal of the slope
so
-3x becomes 1/3x
so
perpendicular : y = 1/3x + 3
Answer:
X=7
Y=9
Step-by-step explanation:
.y=x+2
y = 2x - 5
Use equivalents y=y so you get:
X+2=2x-5
X-2x=-5-2
-x=-7
X=7
Y=x+2=7+2=9
