ANSWER
a=9
EXPLANATION
The given quadratic equation is
If x=1 is a solution, then it must satisfy this equation:
Therefore the value of 'a' is 9

If you divide by 8, you can put the equation into intercept form. That form is ...
... x/a + y/b = 1
where <em>a</em> and <em>b</em> are the x- and y-intercepts, respectively.
Here, your equation would be
... x/(-2) + y/(-4) = 0
The graph with those intercepts is not shown with your problem statement here. See the attachment for the graph.
