What is the -intercept in the equation?

The -intercept of a linear equation is the point where the graph intersects the -axis. In the case of the equation , when , the equation simplifies to . Therefore, the -intercept is , which means the graph crosses the -axis at the point .

To visualize this, imagine a straight line that slopes downward as it moves from left to right, starting from on the -axis. If you were to plot it, you’d see that at the point , the line crosses the -axis. It’s like the line says, “Hey, I’m here at this height when there’s no horizontal movement!”
