Slope equation :
m = y₂-y₁/x₂-x₁
We are given the following points :
(-1, 7) & (4, -1)
Simply plug everything in :)
m = y₂ - y₁ / x₂ - x₁
Plug in :)
m = -1 - 7 / 4 + 1
Simplify.
m = -8 / 5
So, the slope is -8/5
The first answer choice is correct.

Answer:
So the age of Mr.Jones = 39 yrs. |
the age of his wife = 39-4 = 35 yrs.|
and the age his son = 39-31 = 8 yrs.|
Step-by-step explanation:
Let the age of Mr.Jones = x
So, the age of his wife = x-4 (wife is younger by 4 years)
and the age of his son = x-31 (son is younger by 31 years)
Sum of their ages = x + (x-4) + (x-31) = 82
= x + x - 4 + x - 31 = 82 (By removing the brackets)
= 3x - 35 = 82
= 3x = 117 (By adding 35 both the sides)
= x = = 39
