I am supposed to find the slope and y intercept of x=-9
Just waned to verify, but the line would be vertical and so the slope is undefined, but because the line never croses the y-axis how would you verbially say this. Would the y intercept be undefined or never or (i don't know the correct termonology)
Thanks!
The slope is infinity. The y-axis intercept does not exis. Your terminology seems fine to me.
