Answer:
In step 2, she didn’t use an x and y from the same coordinate pair
Step-by-step explanation:
see the attached figure to better understand the problem
we have the points (5, 1) and (3, 5)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute
step 2
The equation of the line in point slope form is

take the point (3,5)
substitute



step 3

therefore
In step 2, she didn’t use an x and y from the same coordinate pair
