Answer:
C.
1 ≤ w ≤ 5
Step-by-step explanation:
Move all terms not containing
w
from the center section of the inequality.
Inequality Form:
1

3x - 7 + 6 = 7x + 6
First shift all the pure numbers to one side
3x = 7x + 6 + 7 - 6
Now add up the pure numbers
3x = 7x + 7
Shift the 7x to the other side
3x - 7x = 7
-4x = 7
Divide 7 by - 4
X = - 1.75
The slope is 2/3 because 3 - 1 = 2 and 0 - -3 = 3
I believe the answer is b
Well maybe because the only thing that is different is the - and +
