Answer: y = x - 9
Step-by-step explanation:
The equation of line slope - point form is given as :
y - [tex]y_{1}[/tex] = m ( x -[tex]x_{1}[/tex]
From the question
m = 1
[tex]x_{1}[/tex] = 9
[tex]y_{1}[/tex] = 0
Substituting into the formula , we have
y - 0 = 1 (x - 9)
y = x - 9
Therefore , the equation of the line in slope - intercept form is given as
y = x - 9
