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

Jun 15, 2018

Gradient $= 2$, Intercept$= - 4$

#### Explanation:

We can rearrange this to be:

$y + 4 = 2 x$

$\Rightarrow y = 2 x - 4$

$\therefore$ The gradient is $2$

$\therefore$ The intercept is $- 4$

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: $y = 2 x - 4$.

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

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

So the slope is $2$.
