Answer:
all in all it's y=x
Step-by-step explanation:
A (4,1); B (0,-2)
G=delta y
--------
delta x
1-(-2)
-------
4-0
3/4=G
3/4=y-1/x-4
4 (y-1)=3 (x-4)
4y-4=3x-12
4y=3x+4-12
y=3/4x-3
The Prove that two non-zero vectors are collinear if and only if one vector is a scalar multiple of the other is given below.
<h3>What are the proves?</h3>
1. To know collinear vectors:
∧ ⁻a ║ ⁻a
If ⁻b = ∧ ⁻a
then |⁻b| = |∧ ⁻a|
So one can say that line ⁻b and ⁻a are collinear.
2. If ⁻a and ⁻b are collinear
Assuming |b| length is 'μ' times of |⁻a |
Then | 'μ' ⁻a| = | 'μ' ⁻a|
So ⁻b = 'μ' ⁻a

Step-by-step explanation:
hello :
x² - 9x = 0
x(x-9)=0
x=0 or x-9=0
x=0 or x= 9
Answer:
Correct choice is D.
.
Step-by-step explanation:
pick any two points from the table say (0,3) and (1,2)
Now we we can use both points to find the equation of line.
slope ![m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-3}{1-0}=\frac{-1}{1}=-1](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%5Cfrac%7B2-3%7D%7B1-0%7D%3D%5Cfrac%7B-1%7D%7B1%7D%3D-1)
now plug slope m=-1 and any point say (0,3) into point slope formula
![y-y_1=m\left(x-x_1\right)](https://tex.z-dn.net/?f=y-y_1%3Dm%5Cleft%28x-x_1%5Cright%29)
![y-3=-1\left(x-0\right)](https://tex.z-dn.net/?f=y-3%3D-1%5Cleft%28x-0%5Cright%29)
![y-3=-1\left(x\right)](https://tex.z-dn.net/?f=y-3%3D-1%5Cleft%28x%5Cright%29)
![y-3=-x](https://tex.z-dn.net/?f=y-3%3D-x)
![y=-x+3](https://tex.z-dn.net/?f=y%3D-x%2B3)
Hence correct choice is D.
