What two numbers add to equal ten and multiplies to equal negative seven?

Okay ShallBeTheLast, what we will do will involve a lot of simple plug and play kind of actions.
To start we must notice one number must be negative and the other should be positive, because the multiplied number is a negative.

Next, lets multiply number that have a sum of 10 (keep in mind one has to be negative and the other has to be positive).

-1 * 10 = -10 false
-2 * 12 = -24 false
-3 * 13 = -39 false
notice that no number working and it's only getting farther away.
There is no solution for this that involves to integers.

I think you might of wrote the question backwards.
If that is the case we would run numbers like
-1 * (-6) = 7 false
-2 * (-5) = 10 true

-2 and -5 would work

Chope you get it right gl

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
