For every cd it cost 8.25
The slope of the trend line is 0.90 ($900), which represents an increase in <em>salary</em> of $900 for every $1,000 increase in <em>annual tuition cost. (Third Option).</em>
<em><u>Recall:</u></em>
- Slope of a trend line usually depicts a unit rate between two variables.
- The equation of a trend line is usually represented in slope-intercept form as, <em>y = mx + b</em>.
- Where, m is the slope, x and y are the two variables that are changing, while b is the initial value.
Given the equation representing the trend line as, s = 0.90c + 26.4
The slope of the trend line would be 0.90, which is $900.
This means that, there is an increase in <em>salary</em> of $900 for every $1,000 increase in <em>annual tuition cost. (Third Option).</em>

The correct answers are x≠2 and x≠(-2).
Domain restrictions are any points in the domain where the function will not have a value. This basically means that it's a point where x won't work in the function.
For the numerator, any value will work for x. We can have a value of 0 in the numerator, or a positive, negative, or decimal number.
However, the denominator cannot equal 0. This is because a fraction bar represents division, and we cannot divide by 0. The values that make the denominator 0 can be found by:
x²-4=0
Add 4 to both sides:
x²-4+4 = 0+4
x² = 4
Take the square root of both sides:
√x² = √4
x = 2 or x = -2.
