Hannah is 1 year old today.
Step-by-step explanation:
Let,
Hannah = x
Biff = y
According to given statement;
y = x+25 Eqn 1
In four years;
y+4 = 6(x+4) Eqn 2
Putting value of y from Eqn 1 in Eqn 2;
Dividing both sides by 5
As x is age of Hannah, therefore,
Hannah is 1 year old today.

Y = -6x - 15
We’re already at -3 (y) and the slope is negative so the y intercept is < -3. X is -2 and we need to find the y when x is 0. -2 is 2 away from 0 and 6 (the slope) times 2 is 12. -3 - 12 = - 15
