Answer:y=-2x-1
Step-by-step explanation:
(1,-3) and a slope of -2
Use Formula
Y= mx +b to find b. By using the slope and point given .
M is slope
Y is -3
X Is 1
Y=mx+b
-3= -2(1)+b
-3= -2+b
-3+2=b
-1=b
Now create the equation by inputting the slope they gave you which is -2 and answer we solved for b which is -1 .
Y= -2x-1
