Y = mx + b
slope(m) = -2/3
(-4,1)...x = -4 and y = 1
now we sub and find b, the y int
1 = -2/3(-4) + b
1 = 8/3 + b
1 - 8/3 = b
3/3 - 8/3 = b
-5/3 = b
so ur equation is : y = -2/3x + (-5/3) which can be written as : y = -2/3x - 5/3

2. 2007-2010
Step-by-step explanation:
just did it edge hope this helps :))
The two numbers are: 21 and 11
Step-by-step explanation:
Let x and y be the two numbers.
x+y = 32
x-y = 10 Rewrite this as x = y+10 and substitute for x in the first equation.
(y+10) + y = 32 Simplify and solve for y.
2y+10 = 32 Subtract 10 from both sides.
2y = 22 Divide both sides by 2.
y = 11
x = y+10
x = 11+10
x = 21
Answer:
33 years
Step-by-step explanation:
I think you might have made a typo, but it would still be 33 if the mean age stays the same.
Equation: 3(2y+4)=4(2y-1/2)
Multiply: 6y+12=8y-2
Combine like terms: 14=2y
Solve: Y=7 :)
