So the answer for #1 is letter C

for #2 is letter D

for #3 is letter B

for #4 are letter A,B,D, and E

anser is a

step-by-step explanation:

negitive slope

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
