Step-by-step explanation:
The lines intersect at the point ![(-1,2)](https://tex.z-dn.net/?f=%28-1%2C2%29)
Explanation:
The given two equations are
and ![y=x+3](https://tex.z-dn.net/?f=y%3Dx%2B3)
We need to determine the whether that they intersect.
To determine the point of intersection, let us solve the equation by substitution method.
Let us equate both the equations.
Thus, we have,
![-2x=x+3](https://tex.z-dn.net/?f=-2x%3Dx%2B3)
Subtracting both sides by x, we get,
![-2x-x=x+3-x](https://tex.z-dn.net/?f=-2x-x%3Dx%2B3-x)
Simplifying, we have,
![-3x=3](https://tex.z-dn.net/?f=-3x%3D3)
Dividing both sides by -3, we get,
![x=-1](https://tex.z-dn.net/?f=x%3D-1)
Substituting
in the equation
, we get,
![y=-2(-1)](https://tex.z-dn.net/?f=y%3D-2%28-1%29)
![y=2](https://tex.z-dn.net/?f=y%3D2)
Thus, the lines intersect at the points
and ![y=2](https://tex.z-dn.net/?f=y%3D2)
Hence, the lines intersect at the point ![(-1,2)](https://tex.z-dn.net/?f=%28-1%2C2%29)
