Answer & Step-by-step explanation:
When we see the phrase "rate of change" then it means that we are looking for the slope. So, we will need to know the formula for finding slope or the rate of change.

Now, let's use this equation to solve for the rate of change of each question.
<u>Problem 1:</u>

<em>The rate of change of this equation is 2/3</em>
<u>Problem 2:</u>
<u></u>
<u></u>
<em>The rate of change for this equation is 2</em>
<u>Problem 3:</u>
<u></u>
<u></u>
<em>The rate of change for this equation is 6</em>
Answer:
Slope: 2
Step-by-step explanation:
The slope of a line is when x increases by an amount, y increases by an amount. We can find the slope of a linear graph by taking 2 points. I will use (0,3) and (-1,1)
We see that the y-values are 4 from each other, and that the x-values are 2 from each other.
Now, we can use a method called rise over run, which is y-value/x-value.

Therefore, the slope is 2.
<u>Answer:</u>
There is only 1 peak in this distribution.
<u>Step-by-step explanation:</u>
In the distribution of exam scores (graded from 0 100) for 86 students 38 students got an A, 28 students got a B, and 20 students got a C.
a) Since, 38 > 28 > 20 , there is only 1 peak for this distribution.
