Answer:
y=-1
Step-by-step explanation:
the y line is the up down (vertical) line x is left right (horizontal) line
y=-1 means that the y value will always be over the -1 point on the x line
x= -1
just by looking at the graph you can see that the equation will be true when x is equal to negative 1
the slope here is undefined and there is no y-intercept, which is why the equation is just x=-1
