Option 1:
is the right answer
Step-by-step explanation:
The slope-intercept form is given by:

Here m is the slope and b is y-intercept
Given
m = -3
Point = (-1,6)
Putting the value of slope

To find the value of b, putting the given point (-1,6) in the equation

Putting the value of b in slope-intercept form

Hence,
Option 1:
is the right answer
