(-2 +4)/2 = 2/2 = 1
(-4-6)/2 = -10/2 = -5
midpoint = (1, -5)

in this, we can simply multiply by -2 at the bottom to get a -4g, and thus "eliminate" the g-variable
Answer:
![y=3x](https://tex.z-dn.net/?f=y%3D3x)
Step-by-step explanation:
⇒ ![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
![3x+y=0](https://tex.z-dn.net/?f=3x%2By%3D0)
Since there are no coefficients on the
, you can convert the equation in one step.
<em>Subtract</em>
from both sides
![y=3x](https://tex.z-dn.net/?f=y%3D3x)
<em>plz mark me brainliest. :)</em>
