Common difference is -2.5
answer is an = 15.5 - 2.5n
That one has to be d because that’s the only one that makes Samar
Answer:
C.
Step-by-step explanation:
<u>Slope</u>
<em>So first we need to find the </em><u><em>slope</em></u><em> in order to answer the question. To find the slope, we need to choose any two points from the table.</em>
<em>The slope equation is </em>.
<em>Let's use point (10,4) and point (15,3).</em>
<em>Now let's substitute those values into the slope equation. That gets to </em>.
<em>Now let's simplify that to </em>. Therefore, the slope is . In other words, it is also .
<u>Point-Slope Form</u>
<em>Now we need to plug in the numbers into the point slope form. </em>
<em>The point-slope form is </em>.
<em>Let's plug in the slope (m) into the equation. That gets to </em>.
<em>Now let's use (-10,8) in the equation since that's what it states in the problem. Doing that would lead to </em>. In other words, that is .
Therefore, the answer has to be c. .
