Answer:
-1
Step-by-step explanation:
you can look at the graph or the equation. input= x value output=y value
y=1/2x-1 is the equation
It says when x is zero what is y so put in 0 for x
y=1/2(0)-1
y=-1

<u>Step-by-step explanation:</u>
The standard form for an ellipse is: where
- (h, k) is the center
- a is the radius on the x-axis
- b is the radius on the y-axis
Given: (h, k) = (0, 0)
a = 8 (distance on x-axis from origin to -8)
b = 4 (distance on y-axis from origin to 4)
Input h = 0, k = 0, a = 8, b = 4 into the standard form for an ellipse:
