Answer:

It is not a solution

Step-by-step explanation:

You have to substitute (2,-1) into y=3x-2

with 2 as X and -1 as y, if it doens't equal 0 then it's not a solution.

another way is to graph it:

If (2,-1) is a point in your line (y=3x-2), it is a solution

What is the solution of −81=b6 ? A. b = −486 B. b = −75 C. b = 13.5 D. b = 486

BartSMP [9]

We have to isolate b to be alone.
Soooo first we divide both sides by 6

-81 = b6
÷6 = ÷6 The right side cancels out and gets the b alone. While we solve the right side of the equal sign.
-81 ÷ 6 = -13.5
So this means we isolated b alone!
b = -13.5

Our final answer is..
b = -13.5
