Answer:
m= -1
b= -3
Step-by-step explanation:
The equation is in point-slope form, which is
y=mx +b
Where m is the slope and b is the y intercept.
Essentially; the number being multiplied by x is the slope, and the number being subtracted or added to x is the y-intercept.
We are given this equation of a line:
y= -x-3
-1 and x are being multiplied. (-1*x=-x). Therefore, the slope is -1. 3 is being subtracted from -x (-3). Therefore the y intercept is -3.
m= -1
b= -3
