Answer:
The answer to your question is: Yes, it is a solution
Step-by-step explanation:
Point (-2, 3)
Line: y = 2x + 7
Process, replace the point in the line
3 = 2(-2) + 7
3 = -4 + 7
3 = 3
As we got that 3 equals 3, then the point given is a solution of the equation.
Answer:
x + 3 = 0.
Step-by-step explanation:
One would be:
x + 3 = 0 Subtract 3 from both sides:
x + 3 - 3 = 0 - 3
x = -3
The discriminant of the equation

is 76.
I hope that helps.
