For this case we have that, the equation of the line in slope intercept form is given by:
[tex]y = mx + b[/tex]
Where:
m is the slope
b is the cut point with the y axis
If we have:
[tex]y-1 = -7 (x-3)[/tex]
We take it in the form [tex]y = mx + b[/tex] we have:
Knowing that [tex]- * - = +[/tex] and applying distributive property to the terms of the parenthesis:
[tex]y = -7x + 21 + 1\\y = -7x + 22\\So,\ b = 22[/tex]
Answer:
Option D
