# How do you find the point of intersection for #3x-y=4# and #6x+2y= -8#?

##### 1 Answer

Intersection point : (0,-4)

#### Explanation:

We want to find the point

The word "intersection", here, is referring to functions :

A function is generally writing :

Then, we need to transform the two equations to something like :

"

Let's define functions

Function

Then we have

Function

Then we have

We can mark here

Then :

The coordinates of

We can check the result with a graph of the situation (Alone, this is not a proof !!)
