Find the slop of the line through (6,-7) and (4,-8)

The slope is 1/2

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=(-8)-(-7)/4-6

m=-1/-2

m=1/2

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
