Answer:
y = -x - 1
Step-by-step explanation:
Slope - Intercept form is y = mx + b
m = slope
b = y-intercept
We already have the slope of -1. Substitute it into the equation.
y = -x + b
To find b, substitute the given point (2, -3) into the equation.
-3 = -2 + b
b = -1
Substitute the value of b into the equation and you are left with:
y = -x - 1
