Answer :
I'm not sure if you're looking for anything more than this, but if you plug in all those values (trail and error) the only one that is successful is (3,-2)
3 + -2 = 1
-3 + -2 = -5
All of those other values are false and do not add up to the correct value.
Ex: (-2,3)
-2+3 = 1 (True)
- -2+3 = 2+3 = 5 (False, not negative. The - -2 becomes positive.)
3 + -2 = 1
-3 + -2 = -5
All of those other values are false and do not add up to the correct value.
Ex: (-2,3)
-2+3 = 1 (True)
- -2+3 = 2+3 = 5 (False, not negative. The - -2 becomes positive.)
d + e = 1
-d +e = -5
If you cross out d and -d, you will have...
e = 1
e = -5
...left. From there, you would add the e's together to give you
e^2 = -4
you would now just divide both sides by 2 and your answer should be e = -2
You then proceed to your answer choices and which ever one has the e-intercept as -2, is your final answer.
I hope this helped! :D
