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
