Answer:
A
Step-by-step explanation:
Difference between (x) & (x')
P - P' = (2 - (-6) , 2 - 2) = (-8,0)
Q - Q' = (5 - (-3), 2 - 2) = (-8,0)
etc...
Always get (-8,0) hence -8 in x-direction
12x+2y=112
6x+y=56
6x=56-y
x=(56-y)/6
y=(56-6x)
Answer: -3
Step-by-step explanation:
Answer:
They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 3 times the second equation of System A.
Step-by-step explanation:
System A
2x + y = 5 --> (1)
−4x + 6y = −2 --> (2)
(1) + 3×(2)
-10x + 19y = -1
System B
−10x + 19y = −1 --> (1)
-4x + 6y = −2 --> (2)
Answer:
y=x-2
Step-by-step explanation:
4-0=4 = (change in y)
2--2=4 = (change in x)
change in y/change in x=4/4=1=x
gradient = x
y=x+c
Subtitute any coordinate
2=4+c
c=-2
so
y=x-2
