# How do you graph y=-2x+3 by plotting points?

Mar 7, 2017

see explanation.

#### Explanation:

Choose any values of x and substitute them into the equation to obtain corresponding value for y

$x = 0 \to y = 0 + 3 \to \left(0 , 3\right) \leftarrow \textcolor{red}{\text{ y-intercept}}$

$x = - 2 \to y = 4 + 3 = 7 \to \left(- 2 , 7\right)$

$x = 2 \to y = - 4 + 3 = - 1 \to \left(2 , - 1\right)$

Plot these 3 coordinate points and you have the graph.
