For this case what we should do is evaluate the corresponding linear function with the following values:
[tex]x = 7
y = 1[/tex]
We must verify that equality is met.
For the following function we have:
[tex]y = -x + 8
[/tex]
Substituting values:
[tex]1 = -7 + 8
[/tex]
Rewriting:
[tex]1 = 1
[/tex]
Therefore, the point (7,1) is on the line.
Answer:
B.) y = -x + 8
