For these types of questions, first, click the line tool palette labelled D2, and a plot by clicking your mouse for the first end-point, moving your mouse down and to the right and clicking again for the second end-point. The new line should be further out than the original.

Ithink the answer would be knew

7p=14 so then you would divide by p=2

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
