How do you graph the line  y = x + 2?

Mar 29, 2017

$y$ is a straight line of slope $1$ and y-intercept of $2$
$y$ has a single zero at $x = - 2$

Explanation:

The equation of a straight line in slope $\left(m\right)$ and y-intercept $\left(c\right)$ form is:

$y = m x + c$

In our example: $m = 1$ and $c = 2$

Hence: $y$ is a straight line of slope $1$ and y-intercept of $2$

$y = 0 \to x + 2 = 0$

$x = - 2$

Hence: $y$ has a single zero at $x = - 2$

These points can be seen on the graph of $y$ below:
