See the explanation.

$y=-1/2x+3$ is the slope intercept form of a linear equation.

Determine two points on the line by substituting values for $x$ into the equation and solving for $y$ . You only need two points for a straight line.

Table of Points
$x=0,$ $y=3$
$x=6,$ $y=0$

Plot the points and draw a straight line through the points.
