Answer:
7x - y = 5
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
obtain the equation in point-slope form, that is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m - 7 and (a, b) = (1, 2), hence
y - 2 = 7(x - 1) ← in point-slope form
distribute and simplify
y - 2 = 7x - 7 ( add 7 to both sides )
y + 5 = 7x ( subtract y from both sides )
5 = 7x - y
7x - y = 5 ← in standard form
