Question

Please help
me answer both of them ASAP!! and submit it like this. Example: 1=b and 2=d

Answer 1

first one: C

second one: A

Explanation:

4a - 5 + 3b - 2 - 2b - 5a

combine a terms:

-a - 5 + 3b - 2 - 2b

combine b terms:

-a - 5 + b - 2

combine numbers:

-a + b - 7 (this is option c)

_____________________

y = mx + b, solve for m

subtract b from both sides:

y - b = mx + b - b

y - b = mx

divide both sides by x:

(y - b)/x = mx/x

m = (y - b)/x (this is option a)

Answer 2

8. -a+b-7

9. m=(y-b)/x
