Answer:
The answer to your question is because it is a solution of each equation.
Step-by-step explanation:
Data
Point (3,4)
Equation l y = 1/3x + 3
Equation ll y = 2x - 2
Process
1.- To test is a point is solution to a system of equations,
-Substitute the point in both equations
Equation l 4 = 1/3(3) + 3
4 = 1 + 3
4 = 4 The point is a solution because
4 = 4
Equation ll 4 = 2(3) - 2
4 = 6 - 2
4 = 4 This point is a solution for the second
equation but not for the first one.
2.- Conclusion
As the point is a solution of each equation, it is a solution of the system.
0+0=0 0+0=0+0
They are all addition, and they are all 0, and since 0 equals nothing, the sum is equivalent to 0!
So we have 299790000, we want to have only one digit in front of the decimal, 2.9979x10^9
hope this helps :)
Zero slope. When it is a straight line across its a zero slope and when it’s up and down its undefined.
