Answer:
Slope = -3
Step-by-step explanation:
The slope is the change in y over the change in x
The slope formula is m=y₂-y₁/x₂-x₁ (y over x)
So, plug in your coordinates (the subscript represents the order in which your points are going to be subtracted in)
So, you would get m=-2-4/1-(-1)
Simplify (first subtract the top, then subtract the bottom)
This would get you to -6/2 (remember your rules: a negative and a negative makes a positive)
-6/2 would get you to -3

Answer:
There are 10 pigs and 30 chickens
Step-by-step explanation:
Let the number of pigs be x
let the number of chickens be y
Then there are 40 heads . So the total number of pigs and chickens is 40
x + y = 40-----------------------(1)
We know that pigs have 4 legs and chickens have 2 legs
4x + 2y = 100----------------------(2)
Solving (1) and (2)
multiply (1) by 2
2x + 2y = 80-------------------------(3)
subtract (3) from (2)
4x + 2y = 100
2x + 2y = 80
----------------------------
2x = 20
----------------------------
x = 10
Now Substituting x in (1), we get
10 + y = 40
y = 40 - 10
y = 30
