# How do you graph y=2x+1 using a table?

Jan 9, 2017

See the explanation.

#### Explanation:

$y = 2 x + 1$

Since this is the slope-intercept equation for a straight line, the table only needs two points. However, I'm going to determine $4$ points (ordered pairs). Determine values of $x$, then calculate $y$.

Ordered Pairs
$x$$\textcolor{w h i t e}{\ldots \ldots .} y$
$0$$\textcolor{w h i t e}{\ldots \ldots .} 1$
$1$$\textcolor{w h i t e}{\ldots \ldots .} 3$
$2$$\textcolor{w h i t e}{\ldots \ldots .} 5$
$3$$\textcolor{w h i t e}{\ldots \ldots .} 7$

Plot the points on a graph and draw a straight line through them.
