Answer:
[tex]y=-9[/tex]
Step-by-step explanation:
We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).
Note that x=1 is a vertical line since x is 1 no matter what y is.
This means that if our new line is perpendicular to the old, then it must be a horizontal line.
So, since we have a horizontal line, then our equation must be our y-value of our point.
Our y-coordinate of our point (8,-9) is -9.
Therefore, our equation is:
[tex]y=-9[/tex]
And this is in standard form.
And we're done!
