# What is the slope and y-intercept of this line 2y = 8?

Apr 17, 2018

y-intercept is 4

#### Explanation:

Given: $2 y = 8$

Divide both sides by 2

$y = 4$

Notice there are no $x$ terms so write it as:

$y = 0 x + 4$

Compare to: $y = m x + c$ where $m$ is the gradient and $c$ is the y-intercept

$y = 0 x + c$
$y = 0 x + 4$

The slope ($m$) is $0$ from $0 x$ so it is parallel to the x-axis.

y-intercept$= c = 4$
