Given: `x+2y-3=0`

Rewrite the equation in slope intercept form: `y=mx+b`

The variable m represents the slope and the variable be represents the y intercept.

You will rewrite the equation in slope intercept form by isolating the y variable.

`x+2y-3=0`

`2y=-x+3`

`y=(-1/2)x+(3/2)`

The slope is -1/2.
