Answer:
substitute y = mx +b = (2/3)x -2
Step-by-step explanation:
slope intercert form looks like this
y = mx + b
m is the slope
b is the y intercept
The line intercepts the y at -2
To find slope, pick 2 points to find the slope
m = (y2 - y1)/(x2-x1)
i select point 1 (0,-2) and point 2 (3,0)
m = (0-(-2))/(3-0) = (2)/3
substitute y = mx +b = (2/3)x -2
C = 3b+2d is the same as 3b+2d = C
Let's isolate d. To do this, we first need to subtract 3b from both sides
3b+2d = C
3b+2d-3b = C-3b
2d = C-3b
Then divide both sides by 2
2d = C-3b
2d/2 = (C-3b)/2
d = (C-3b)/2
Take note of the parenthesis as they are very important. We want to divide ALL of C-3b over 2. We don't want to just divide -3b over 2.
The answer choices you have aren't 100% clear but I have a feeling your teacher meant to say d = (C-3b)/2 instead of d = C-3b/2 for choice A
If that assumption is correct, then the answer is choice A.

Step-by-step explanation:
It's hard to tell what you mean. I'm going to assume you mean that you want what is left to be 3/7 less.
1400 - 3/7 1400 = 1400 - 600 = 800
