Question

Find the y-intercept
of the line on the
graph?

Answer 1

9514 1404 393

Answer:

(0, -3)

Explanation:

The y-intercept is the point where the graph crosses the (vertical) y-axis. That point is halfway between grid lines marked -2 and -4, so is at the grid line with the value -3. The x-coordinate there is 0, so the y-intercept point is ...

(x, y) = (0, -3)

_____

Since the y-intercept always has an x-coordinate of 0, we sometimes refer to the y-intercept using only the y-value: -3.
