Notice that
so on the left side, a factor of <em>x</em> - 7 in the numerator and denominator can cancel
But we can only cancel them out as long as <em>x</em> ≠ 7 (because otherwise we'd have the indeterminate form 0/0 on the left side).
So, the equation is true for all <em>x</em> <u>except</u> <em>x</em> = 7. In set notation,
In interval notation,
We can write it down as a fraction:
and we can simplify this fraction:
=
=
=
or we can write it as a decimal:
0.1282...

Step-by-step explanation:
Explanation: The y axis is the line that goes up and down, vertical. The x axis is the line that goes straight across, horizontal. So, when looking for intercepts we have to see what numbers your graphed line goes through.
Make sure when you are writing your points you write it in (x,y) form. If you don't it will be wrong.
So, for our x intercept it would be -7,0.
This is because your graphed line goes through x at -7 and it has no y, so that would be 0.
For your y intercept, it would be 0,2
This is because our line does not go through x, so we make that 0. It does go through y at 2.
Hope this helps :)
If you need elaboration on anything let me know. I know sometimes with math it is kind of hard to explain through typing.
