Analyzing the table given in the exercise, you can identify that each input value (x-value) has one and only one output value (y-value). Therefore, the relation is a function.
Notice that "x" is the Independent Variable and "y" is the Dependent Variable.
• Observe that when:

The value of "y" is:

Therefore, the Start value is:

• To find the Rate of change you can follow these steps:
- You can identify these ordered pairs:

If you plot them on a Coordinate Plane, you get:
You can identify that it is a line. Therefore, the Rate to change can be found with this formula:

In this case, you can choose these points:

And set up that:

Then, substituting and evaluating, you get:

• To find the equation for the relation, you need to remember that the
equation of a line can be written in Slope-Intercept Form:

Where "m" is the slope (the rate of change) and "b" is the y-intercept (the start value).
Since you already know both values, you can set up that the equation is:

• To find the value of "y" when:

You need to substitute that value into the equation and then evaluate:

Hence, the answers are:
• Start value:

• Rate of change:

• Relation:

• Table:
