Answer: Y=-1/4x
Step-by-step explanation:
A good way to find an equation of a line is to look for the slope. An obvious spot on this line would be when it crosses (0,0), and another one to the right would be when it crosses at (4,-1).
The slope is rise over run, or if we use the two points we found, "rise" would be -1, because it's dropping 1 unit when going from (0,0) to (4,-1), and the "run" would be 4, because it moves to the right 4 from (0,0) to (4,-1).
Putting these two values together we get:
m (slope) = rise / run
m = -1 / 4
Out of all the equations we're given, we can look for the one with a slope of -1/4, which is given to us:
y = (-1/4)x

Let's solve this in two parts, first the equation. Let x represent the ages of the daughters, so the equation is
x + (x+2) + (x+4) = 60
Next let's calculate the ages.
3x+6=60
3x=54
54/3=18, therefore x=18
x=18
x+2=20
x+4=22
So the ages of the daughters are from youngest to oldest are 18, 20, and 22
