Question

Anyone? I need real answers no links plz :/

Answer 1

1. y = 2x

2. y = 1/5(x)

3. y = -3x

4. y = 4x

Explanation:

All of these lines are proportional, so they're in the form of y = kx where k = constant of proportionality.

Slope Formula:
`(y_2-y_1)/(x_2-x_1)`

1.

• 
  `(4-0)/(2-0)`
• 
  `4/2`
• 
  `2`
• y = 2x

2.

• 
  `(1-0)/(5-0)`
• 
  `1/5`
• y = 1/5(x)

3.

• 
  `(-9-0)/(3-0)`
• 
  `-9/3`
• 
  `-3`
• y = -3x

4.

• 
  `(-8-0)/(-2-0)`
• 
  `-8/-2`
• 
  `4`
• y = 4x

Have a lovely rest of your day/night, and good luck with your assignments! ♡
