Answer:
-2a + 4b - 3c.
Step-by-step explanation:
(2a+3b-c) - (4a-b+2c)
Distribute the negative over the second parentheses.
= 2a + 3b - c - 4a + b - 2c
= -2a + 4b - 3c.
Slope is 1… I would explain but thats alot of work… hope this helps

Answer:
A (-1,0)
B (-1,-5)
Step-by-step explanation:
Just took the quiz
A.) b = 0.7a
d) 1a = b
These two equation shows the direct variation. with the coefficient of a as the constant of variation.
y = kx ; where k is the constant of variation. y directly varies with x at the rate of k.
b = 0.7a where b represents y ; a represents x; and 0.7 represents k.
1a = b where b represents y ; a represents x ; and 1 represents k.
