Yo sup??
given line is x=3
this is a line which is parallel to the y axis.
Since it's parallel to the y axis it's slope is infinity.
Hope this helps.
Answer:
X would have to equal 6. To work it out, you subtract 4 from each side to cancel out the 4. -x = -6. You have to make -x just x so you × each side by -1. You get x = 6.
The sum of n terms of a geometric series is given by

Substituting the given numbers, you have

There are 6 terms in the series.

a parallel line to that one above, will have the same exact slope, since parallel lines have the same slope.
