Answer:
Step-by-step explanation:
We can write the equation using the point and the slope .
Formula we need to use is the point slope formula
Which is given by
Y-y1= m(X-x1)
Here given that (x1,y1)=(1,-1) and m = -3
x1= 1
y1 = -1
so equation is
Y-(-1) = -3 (x-1)
Distribute the slope
y+1 = -3x+3
y= -3x+3-1
y = -3x + 2
So the equation is
y =-3x +2
