Question 57236
Hi Ashley,
Can someone help me find the slope and y-intercept on:

    x = -9
This is a special case, when there is only and x, a number and no y, you have a vertical line going through -9.
Vertical lines have undefined slopes and don't cross the y axis.
In other words, there is no y-intercept and the slope is undefined.
Happy Calculating, Ashley!!!
