Answer:
true
Step-by-step explanation:
Answer:
B. x ~ 5
Step-by-step explanation:
This is a right isosceles triangle!
Perpendicular has slope that mutiplies to -1 to the other slope
for
ax+by=c
slope=-a/b
-1x+3y=9
-(-1)/3=1/3
1/3 times what=-1?
-3
y=mx+b
m=slope
y=-3x+b
find b
(-3,2)
(x,y)
x=-3
y=2
2=-3(-3)+b
2=9+b
mnus 9
-7=b
equaton is
y=-3x-7 or
3x+y=-7
