<u>Answer:</u>
- x = 0
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Formula: y = mx + b
<em>If the line is a vertical line on a graph, then this means that the </em><em>x coordinate is 0</em><em> while the </em><em>y-intercept is un-identified.</em><em> Looking at the options and the formula, </em><em>x = 0 </em><em>is the most reasonable option because a </em><em>vertical line on a coordinate plane basically defines that the x coordinate is 0.</em>
Hence, x = 0 must be correct.

Step-by-step explanation:
<u>Functions and Relations</u>
A set of values A can have a relation with another set B as long as at least one element of A has at least one image in B. Functions are special relations where each element of A (the domain of the function) has one and only one image on B (the range of the function).
By looking at the options, we can see that x=9, x=-8, and x=-1 already have defined values in Y, so if we define another value for any of them the relation will stop being a function. The only possible choice to preserve the function is the option
Hope this helps. It has the y and x intercepts on the graph.
