True
Y=-2x-3
Y=-x-2 (rearranged for y intercept form)

Insert -1,-1 into both

-1= -2(-1) -3
-1=-1

Y=-x-2
-1=-1(-1) -2
-1=-1
Both equal

Answer:

true

Step-by-step explanation:

-2×(-1) - 3 = 2 - 3 = -1 then (-1 , -1) is a solution of the equation y = -2x - 3

(-1) + (-1) = -2 then (-1 , -1) is a solution of the equation -2 = x + y

Therefore, (-1 , -1) verify each equation of the system.

Conclusion:

(-1 , -1) is a solution of the system :

y = -2x - 3

-2 = x + y

Choose the function that represents the data in the table.

viva [34]

$y = 2 {x}^{2} - 3$

$\huge\underline\mathtt\colorbox{cyan}{Explanation thing:}$

Using hit and trial, you van find it pretty easily-

Putting x=0, we get y=-3
Putting x=1, we get y=-1
Putting x=2, we get y=5

You can try it for yourself as well, for me, I couldn't find any other option appropriate.
