For homework Tina is asked to write down the opposite value for each number listed which comparison did Tina write incorrectly
1 answer:
In writing down the opposite value of each number, the comparison Tina wrote incorrectly is: Comparison X
<em><u>Recall:</u></em>
- Opposite values of a number are numbers that are of the same distance from point zero on a number line.
- For example, if a is a number, the opposite of a is -a. Or if -3 is a number, the opposite of -3 is 3 because -3 and 3 are both 3 units away from point zero on a number line.
Thus, Tina's comparison is given in the diagram attached below.
The comparison labelled X is incorrect because -(-9) = 9. Opposite of 9 is -9.
Therefore, in writing down the opposite value of each number, the comparison Tina wrote incorrectly is: Comparison X

The equation:
Step-by-step explanation:
Given
The attached table
Solving (a): The rate of change (m)
This is calculated as:
Where:
So:
Solving (b): The initial value
Here, we make use of point (0, y) to calculate the initial value:
Where
So:
Multiply both sides by 3
Solving (c): The equation
This is calculated using:
Where:
So, we have:
