Answer:
Your answer would be 1/-2, or -.5
Explanation:
Since there is only two numbers you use them to solve the equation together.
You alreadey know that ou the x-intercepte to be 3 and the y-intercept to be -6.
So you bring them together as one in a fraction, 3/-6, 3 being an x-intercepte will be on top and the y-intecept will be on bottom.
Now you just solve.
If you put it in a calculator it will come out as, -.5, but if you wanted to keep it in a fraction form it will need to be in half, 1/-2.
