Linear equations are represented by straight line.
The required graph is graph (a).
The given parameters are:
Let x represents the number of weeks, and y represents the number of words in week x.
So, we have:
Substitute 15 for Rate
The above equation means that:
The graph that represents the above ordered pair is graph (a).

Answer:
; 3
Step-by-step explanation:
In this question, we're being asked to write an equation using the word format. Let's find key words in the statement.
The <u>sum</u> of a <u>number x and 4</u>, <u>all divided by 3.</u>
<u></u>
Looking at the wording, we can conclude that we are adding x and 4, and dividing that by 3. So here's how the phrase would look as an expression.
(x+4) or
Now, there's another part to this problem. We must evaluate the value of the expression if x is given to be 5. So let's plug it into our equations.
<u>(5)+4</u>
3
9/3 gives you 3, so your answer would be 3.
