Answer:
Step-by-step explanation:
The equation of the line that passes through the points
(-4,-7) and (8,-13)
is
y=-1/2x-9
--------------------------------------------------------------------------
Define x :
--------------------------------------------------------------------------
Let Charmaine's age be x
Charmaine = x
Shaun = x + 4
--------------------------------------------------------------------------
Construct equation :
--------------------------------------------------------------------------
Sum of their age is 16
x + x + 4 = 16
2x + 4 = 16
2x = 12
x = 6
--------------------------------------------------------------------------
Find their Charamine's and Shaun's age
--------------------------------------------------------------------------
Charmaine = x = 6
Shaun = x + 4 = 6 + 4 = 10
--------------------------------------------------------------------------
