2 important information that we'll look out for a graph: y-intercept and x-intercept 1. Check the y-intercept, you are informed that c < 0, where would you position "c"?

2. To find the "x-intercept", you've attempted to substitute some possible a and b values to give you an idea what it could be. This is a good strategy. However, you need to remember that, the question uses general values, so you need to generalise it in terms of "a", "b" and/or "c" when indicating the "x-intercept".

On the other hand, you have labelled the lines correctly :)
