Question

Is this true or false need answer asap

Answer 1

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 2

true

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
