We are given a system of equations,
This will translate into a 2x2 matrix of coefficients (because 2 equations and 2 unknowns),
The matrix will then be applied to the vector (lower dimensions on top),
And the result vector will be whats on the other side of equals sign,
So to put everything together,
Hope this helps :)
Answer:
The correct option is first graph.
Therefore,
The two points for the line y+5=-2(x-4) ( red color )line are
point A( x₁ , y₁) ≡ ( 0 , 3) .......Blue color
point B( x₂ , y₂) ≡ ............Green color
The Graph is attached below.
Step-by-step explanation:
Given:
Which can also be written as
.....Equation of line
Let the points be point A, and point B
To Find:
point A( x₁ , y₁) ≡ ?
point B( x₂ , y₂) ≡ ?
Solution:
For Drawing a graph we require minimum two points but we will have here three points.
For point A( x₁ , y₁)
Put x = 0 in the given equation we get
y = -2 × 0 +3
y =3
∴ y = 3
∴ point A( x₁ , y₁) ≡ ( 0 , 3)
For point B( x₂ , y₂)
Put y = 0 in the given equation we get
0 = -2x + 3
∴ point B( x₂ , y₂) ≡
Therefore,
The two points for the line y+5=-2(x-4) ( red color )line are
point A( x₁ , y₁) ≡ ( 0 , 3) .......Blue color
point B( x₂ , y₂) ≡ ............Green color
The Graph is attached below.
