To find slope of two points we will need to use this equation: 
( 6 , -12 ) ( 15 , -3 )
Now let's replace the equation with the numbers. (it will be a fraction).
= 
The equation equals 9 over 9, which also equals 1.
The slope of the line is 1.
Answer:
3/10
Step-by-step explanation:
Subtract the sum of 1/3, 4/15 and 1/10 from 1:
10/30 + 8/30 + 3/30 = 21/30, or 7/10
Then: 1 - 7/10 = 3/10
Answer:
84
Step-by-step explanation:
Given,
Length of the print(l) = 24 inches
Width of the print(b) = 18 inches
Perimeter of the print(P)= ?
We know,
Perimeter of the print(P) = 2(l + b)
= 2(24 + 18)
= 2(42)
=84 inches^2
