# How do you graph y = 2 - 2x?

Feb 14, 2017

Refer to the explanation.

#### Explanation:

$y = 2 - 2 x$ is the same as $y = - 2 x + 2$, which is the slope-intercept form of a linear equation, $y = m x + b$, where $m$ is the slope and $b$ is the y-intercept. In the given equation, $m = - 2$ and $b = 2$.

In order to graph a linear equation, you need to find at least two points on the graph, plot the points on the graph, then draw a straight line through those points.

To find the points, pick values for $x$, and solve for $y$ using the equation $y = - 2 x + 2$.

Point 1
x=0;$y = 2$

Point 2
x=1;$y = 0$
