Maggie’s brother is 12 years younger that three times her age . The sun of their ages is 44 . How old is Maggie
meriva
I'm not sure if this is right but you can set up an equation and solve to find Maggie's age:

Maggie's brother's age = b
Maggie's age = m

b = 12 - 3m
44 = 12-3m
12-3m = 44
-12 -12
-3m = 32
÷ 3 ÷3
m = 10.67

So this would be Maggie's age

I hope this helped :)

Y= 1/2x-3<br><br> Slope (m)=<br><br> Y-intercept (b) = <br><br> Which do we use first?
Kaylis [27]

slope (m) = 1/2

y-intercept (b) = -3

You use the y-intercept first to find the first point of (0, -3). From there you can use the slope to find the other points.
