Answer: The line is decreasing.
Step-by-step explanation:
Since we have given that
[tex]4x+y=-3[/tex]
If we write it in point-slope form : we get
[tex]y=-3-4x\\y=-4x-3[/tex]
And our standard form is :
[tex]y=mx+c[/tex]
Equating both the equations, we get that
Slope of line = m = -4
Since the slope of line is negative i.e. m= -4
Then the Line is falling.
Hence, The line is decreasing.
