Answer:
y+21 = -4(x-7)
Step-by-step explanation:
well first you need to find slope what is y2-y1 over x2-x1
23-(-21) ----> 23+21 = 44
-4 - 7 ---> -4 + -7 = -11
so it 44/-11 = -4 is the slope
now choose one pair of points like 7 , -21 and plug them in
y-y1 = m(slope)(x-x1)
so it be y+21 = -4(x-7)
also remember two negatives = a postitive
Answer:
The slope is 1
Step-by-step explanation:
M= Y2-Y1/X2-X1
M= 12-10/7-5=2/2
2 Divided by 2 =1
Slope= 1

Answer:
Answer: 84 meters squared. (i.e. 84m^2).
Step-by-step explanation:
Area of the path = total area of path and plot - plot area only
First, let’s find the area of the plot:
20m x 20m = 400m^2
The path is 1m wide and runs all the way around, so, it describes an ‘outer square’ of 22m x 22m (2 x 1m larger because there are 1m of the path on each side).
The area of this ‘outer square’ is equivalent to the ‘total area of path and plot’
22m x 22m = 484m^2
So:
Area of the path = total area of path and plot - plot area only
= 484 - 400 = 84m^2
