Multi-step Equation

3 – 5 b + 2 b = -2 -2(1 – b) Distribute

3 – 5 b + 2 b = -2 -2(1 – b) 3 – 5 b + 2 b = -2 -2(1) -2(-b) 3 – 5 b + 2 b = -2 -2 + 2 b Distribute

3 – 5 b + 2 b = -2 -2 + 2 b 3 -3 b = -4 + 2 b Combine Like Terms

3 -3 b = -4 + 2 b +3 b 3 = -4 + 5 b Move variable to one side

3 = -4 + 5 b +4 +4 7 = 5 b Move constant to one side

7 = 5 b Multiply or Divide the coefficient

Constant Rate of Change

As the number of transactions Increases by 3, the balance in the account decreases by $30

◦ As the number of transactions Increases by 3, the balance in the account decreases by $30

◦ Since the rate of change is constant, this is a linear relationship.

◦ Since the rate of change is constant, this is a linear relationship. ◦ Let’s check by graphing, next. It is not proportional because the unit rates are different and the line does not pass through the origin.

Method 1 to find slope of a line

Method 1 to find slope of a line Rise = 2

Method 1 to find slope of a line Run = 3 Rise = 2

Method 1 to find slope of a line ◦ Line is upward, so slope is positive Run = 3 Rise = 2 ◦ ◦

Example 2 Rise = -2

Example 2 Rise = -2 Run = 1

Example 2 ◦ Line is downward, so slope is negative ◦ Rise = -2 Run = 1 ◦ So slope is -2
