Answer:
Step-by-step explanation:
Point-slope is:
<h2>
Our goal: </h2>
We have to complete the point-slope equation of the line through (1,3) (5,1).
--------------------------------------------------------
We have a incomplete equation of the line.
We need to find the <u>slope</u> of the line, and the <u>value</u> of .
--------------------------------------------------------
<h3>Finding 'x1':</h3>
It seems that the value of 3 was used to be . This means that the point was used for the equation. This means that would have to be 1.
<h3>Finding Slope:</h3>
Slope is rise over run.
We are given the points (1,3) and (5,1).
The slope is one-half.
--------------------------------------------------------
We now have enough information to complete the point-slope equation.
Our final equation is:
