Answer:
one point (2,-1) with a slope of -3
the equation is based on Y=mx+c
#before that equation We have to find y-intercept which is C here
✔ Y=mx+c here x=2, y=-1 and m(slope) =-3
so
y=mx+c = -1= -3(2) +c= -1= -6+c
there c=5
# Now we can form the equation since we have solved C
✔Y=mx+c = y= -3x+5
