Answer:
Step-by-step explanation:
We can rewrite the square root of negative 18 as . We can evaluate these two quantities separately. The square root of 18 can be factored to get 3 squared times 2. We can take the 3 out to get
. Now, the square root of negative one can be rewritten as
, so this is equal to
Because the answers are all in standard form, we can simply look for the intercepts of the graph.
x-int = (-6, 0)
y-int = (0, -2)
You must multiply these numbers by a coefficient to equal 12:
Solve both equations by dividing by their values:
Look for the answer with these coefficients. The answer is -6x - 2y = 12.
