In the year 1995, there were 1200 students at pine elementary school. in the year 2010 there were 1500 students. find the rate of change from 1995 to 2010 and then model the data with linear function. let x equal the years and y equal the number of students

The rate of change from 1995 to 2010 is 20 students per year and the linear function that models the data will be:

Explanation

In the year 1995, there were 1200 students and in the year 2010, there were 1500 students.

If represents the year and represents the number of students, then two points in form of will be: and

So, the rate of change or slope = (change in value of y / change in value of x)

Now, plugging  slope = 20 and first point  into point slope form of linear equation , we will get.....

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
