Question

How do you graph and find the intercepts for `y = -2.5`?

Answer 1

See a solution process below:

Explanation:

This equation shows for each and every value of `x`; `y` has the same value of `-2.5`. We can graph this equation as:

graph{(0.0000000002x+y+2.5)=0 [-10, 10, -5, 5]}

As you can see from the graph, this is a horizontal line.

The `y`-intercept is at `(0, -2.5)`

graph{(0.0000000002x+y+2.5)(x^2+(y+2.5)^2-0.035) = 0 [-10, 10, -5, 5]}

Because this is a horizontal line there is no `x`-intercept.
