Question

Finding the y-Intercept

You have discovered another alien. Find the correct rescue path before answering this question.

When the spaceship starts from a point on the y axis, what is the y-intercept of the line of travel?

the x-coordinate of the spaceship
the y-coordinate of the spaceship
the y-coordinate of the alien
the distance from the spaceship to the alien

Answer 1

The y-coordinate of the spaceship.

Reason: if the spaceship starts on the y-axis at (0, y0), that point is the line's y-intercept, so the intercept equals the spaceship's y-coordinate.
