Answer:
20
Step-by-step explanation:
Since that is a true equation, you can substitute 7x - 7 y for 4 and simplify.
5(7x - 7y)
5(4)
20
Answer:
The answer to your question is: the points are not collinear.
Step-by-step explanation:
Data
AB = 7
BC = 4
AC = 9
Are points A,B and C collinear?
If they are collinear, the distance from AB plus the distance BC must be equal to the distance AC.
Process
dAB + d dBC = d AC
7 + 4 = 9
11 = 9
The distances are different so they are no collinear
Answer:
Infinitely Many Solutions
Step-by-step explanation:
-3x+y=-9
3x-y=9
--------------
0=0
Y=-1/2x+8
perpendicular means slope is opposite reciprocal so it would be -1/2
y=-1/2x+b
Plug in points and solve for b
B=8
