Find the slope and y-intercept. x=-9

With only this information, you will have a vertical line that will not intercept the Y-axis.

I hope this helps. Thanks for asking.

The slope is infinity and, as PsyDAG has already stated, there is no y-intercept for that line because it is parallel to the y axis.

To find the slope and y-intercept when given the equation x = -9, we need to rewrite the equation in slope-intercept form, which is y = mx + b. However, since x = -9, there is no y variable involved, and therefore the equation does not represent a linear relationship.

In slope-intercept form, the slope (m) represents the rate of change of y with respect to x, and the y-intercept (b) represents the point where the line crosses the y-axis. Since there is no y variable in a vertical line represented by x = -9, there is no slope or y-intercept.

In summary, when given the equation x = -9, the line is vertical, and therefore it has no slope or y-intercept.
