Please see below.

.

$y=2x-3$

Because both $x$ and $y$ have power of $1$ , this is the equation of a straight line. We identify two points on the line and connect them together.

The easiest way to do this is to plug in $0$ foe $x$ and solve for $y$ . Then plug in $0$ for $y$ and solve for $x$ :

$x=0, :. y=-3$ Point $(0,-3)$ is a point on the line.

$y=0, :. x=3/2=1.5$ Point $(1.5, 0)$ is a point on the line.

Let's locate these two points on the $xy$ coordinate system and connect them together:
