Hello!
To find our answer, let's plug this point into the equation and find the y-intercept.
-6=-3(4)+b
-6=-12+b
b=6
As you can see, 1 has the y-intercept +6.
Therefore, our answer is
I hope this helps!
(y - yo) = m.(x - xo)
Where yo and xo the coordinates of one point of this line and m the slope.
(y - (-6)) = -3.(x - 4)
y + 6 = -3x + 12
y = -3x + 12 - 6
y = -3x + 6
