Must m, in the equation y=mx+b=, always be a positive number?
Nadya [2.5K]

Of course not. 

If the line rises higher as it goes from left to right,
then its slope ( 'm' ) is positive.

If it sinks lower as it goes from left to right,
then its slope ( 'm' ) is negative.

Example<br>2 (3x+11)=10​
Bumek [7]

Answer:

x = -2

Step-by-step explanation:

2 (3x+11)=10​

Divide each side by 2

2/2 (3x+11)=10​/2

3x+11 = 5

Subtract 11 from each side

3x+11-11 = 5-11

3x = -6

Divide each side by 3

3x/3 = -6/3

x = -2
