The general equation of a line is y=mx+b
We already that m=-4 so let's plug that in
y=-4x+b
We need to find the value of b to make the equation correct.
Replace the variable x and y with the point value.
1=-4(1)+b
1=-4+b
Add 4 to both sides
5=b

Thus the equation is y=-4x+5

Let's doublecheck
1=-4+5

1=1

POIN-SLOPE Intercept Form: y=mx%2Bb
Thru points (1,1), with m=-4
1=-4%281%29%2Bb
b=1%2B4=5
Then, --------->highlight%28y=-4x%2B5%29,Answer
