What is the slope of the line described by the equation below? y=-x+8

We know that the Standard form of the line is : y = mx + c

Given Equation of the line is : y = -x + 8

Comparing with the Standard form, we can notice that : m = -1

So, the slope of the given line is -1

A is the Answer

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
