Answer:
Multiplication property of equality
Step-by-step explanation:
Given
Step 4: b = -27/8
Required
Which property justifies it?
First, it should be noted that step 4 is a result of step 3
When step 3 is multiplied by 3/8 on both sides, we have step 4;
i.e.
<em>The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality</em>
To solve this problem you must apply the proccedure shown below:
1. By definition, the rate of change of a linear function is the slope of the line and it is constant. Based on this, you must find the slope of the given function.
2. You have the equation of the line has the following form:
Where is the slope and
is the y-intercept.
3. Then, you have that the slope of the function is:
Therefore, the answer is:
