For this case we have that by definition, the slope of a line is given by:
Where:
and
are two points through which the line passes.
According to the figure we have to, the line goes through:
Substituting we have:
Thus, the slope of the line is -1.
Answer:
Answer:
Perimeter of the rectangle=6x+8 square units
Step-by-step explanation:
Given that area of rectangle is
Area of rectangle=lw square units
Comparing the above equation with the given area we get
lw=(x+3)(2x+1)
Therefore length=x+3 and width=2x+1
To find the perimeter :
Perimeter of the rectangle=2(l+w) square units
Therefore perimeter of the rectangle=6x+8 square units
