Answer:
y = -x - 1
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
On the graph, the point on the y-axis is the y-intercept. That point is (0, -1). So the y-intercept is -1.
To find the slope, find two points and put it in the slope equation.
Point A: (0, -1)
Point B: (-1, 0)
m =
Point A:
Point B:
m =
m =
m = -1
y = -1x - 1
In other words, y = -x - 1
