To find the slope of this linear equation, we can rewrite this into the slope-intercept form, as follows:
[tex]2x+y=-3\Rightarrow y=-3-2x\Rightarrow y=-2x-3[/tex]In the slope-intercept form, we can say that the slope for the line is m = -2.
Therefore, the slope for this line is m = -2.
We have to remember that the slope-intercept form of the line is:
[tex]y=mx+b[/tex]Where m is the slope of the line and b is the y-intercept of the line.
