=====================
The gradient, or slope, is the change in y/(change in x)
Usually called m.
m = (-3-3)/(4-4) = -6/0
That's undefined.
The slope is infinite.
It's a "vertical line" parallel to the y-axis.
The equation is x = 4

Some tutors tend to answer some types of problems, and not others.
Posting 5 different problems reduces the chances of getting a response. Post them separately.

Logging onto the site shows the last 50 problems posted. Other problems scroll off, and a tutor seldom goes thru the steps to see them.

Also, Using all CAPS seems to irritate some tutors. Don't do that. What does that accomplish anyway?
