Answer:
x = -3
Explanation:
the lines in the form:
y = a , where a is a constant is a horizontal line
and
x = b, where b is a constant is a vertical line
To find lines that are parallel to the horizontal and vertical lines with point given (n,p), we follow the rule below:
1. If we have a line y = a and goes through point (n,p), the parallel line will have equation y = p
2. If we have a line x = b and goes through the point (n,p), the parallel line will have equation x = n
Now, this question gives a vertical line x = -11 and we need to find line parallel to this that goes through (-3,9). So, from RULE #2 above, we can say the parallel line's equation would be:
x = -3
