Question

How do you find the slope and y intercept for `2x-y=4`?

Answer 1

Gradient `=2`, Intercept`=-4`

Explanation:

We can rearrange this to be:

`y+4=2x`

`rArr y=2x-4`

`therefore` The gradient is `2`

`therefore` The intercept is `-4`

Answer 2

Slope: `2`, Y-intercept: `-4`

Explanation:

For the y-interception just check what `y` is when `x=0`.
This can be done by rearanging the equation by first adding `y` to both sides, then subtracting with `4`.

This will result in: `y=2x-4`.

When `x=0`, `y=-4`.

The slope is basicly the constant infront of the `x` (when simplified to the `y=ax+b`).

So the slope is `2`.
