Find the slope x +3y=-1

well fist we need to change this into slope intercept form

which is y=mx+b

now am going to  change the equation given when "1" is the y value "x" is the x value and "3" is the slope:

x+3y= -1

when is solve this, will get

y=-1 -x /3

y= -1/3x -1/3

so as a result, the slope is -1/3

plz mark brainliest :)

  see below. The solution is the doubly-shaded area.

Step-by-step explanation:

Each boundary line will be dashed, because the "or equal to" case is not included. Each shaded area will be above the corresponding boundary line because the comparison symbol is y > .... That is, only y-values greater than (above) those in the boundary line are part of the solution.

Of course, the boundary lines are graphed in the usual way. Each crosses the y-axis at the value of the constant in its equation. Each has a slope (rise/run) that is the value of the x-coefficient in the equation.
