Answer:
to have an infinite number of solutions, the lines have to be on top of each other.....basically, they have to be the same line.
y = 3x - 1
-3x + y = -1.....multiply by -1
3x - y = 1 <== this would be ur other equation because if u put this in slope intercept form (y = mx + b), it would be the same as y = 3x - 1
Step-by-step explanation:
Answer:
B. y-7 = 1/2(x+3)
Step-by-step explanation:
The coordinates in the question must be inverted (so -3 would become +3 and +7 would become -7)
We know that the line would be perpendicular when (x+3) is preceded by -2
You can double check this by going to a website that graphs equations and overlapping the lines.
Answer:
C is the answer
C ) y = 
Step-by-step explanation:
2 y - x =
( -y + 1)
(2 y - x ) 4 = 3 ( -y +1)
8 y - 4 x = -3 y + 3
8 y + 3 y = 4 x + 3
11 y = 4 x + 3
∴ y =
