Answer:
b = - 21
Step-by-step explanation:
calculate m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (- 6, 3)
m = 
= 
= - 4
y = - 4x + b ← is the partial equation
to find b substitute either of the 2 given points into the partial equation
using (- 4, - 5 ), then
- 5 = 16 + b ⇒ b = - 5 - 16 = - 21
the answer is 9 u just need to find two number multipy to 81
Number 1 and 2 are simillar and 5 and 6 are not simmilar
Segment GZ and Segment XY
I hope that this helped you!
The correct answer for the question that is being presented above is this one: "3"
(1) First get the mean: 25 + 36+ 31 + 32 / 4 = 31
(2) Find the distance of each value to the mean: 31-25= 6; 36-31=5; 31-31=0; 32-31=1
(3) Get the mean of the distance: 6 + 5 + 0 + 1 / 4 = 3
