$2/1x$ is the slope and the $y$ intercept is $(0,-3)$
graph{y=2x-3 [-11.25, 11.25, -5.625, 5.625]}

The equation is in $y=mx+b$ form. This form of graph is super easy to graph when you understand what each part of the equation means.

M - the M stands for the slope of the line

For example if the M was replaced with 3/2 then you would go up 3 and then go over 2 in the positive direction

If the slope is a negative like -4, then you would go down 4 and over 1 in the positive direction

b - the b stands for the y-intercept

For example, if the b was replaced with a 7, you would start at the origin, and move up 7.

If the y-intercept was negative like -5 then you would start at the origin, and move down to 5.
