Answer: 
- Grayson had 10 inches of snow in his lawn 
- the snow falls at a constant rate of 0.5 inches per hour 
- no snow was melting 
- the snow has fallen for 3 hours  
Let y be the height of the snow in the lawn 
Grayson had 10 inches at the beginning (at t=0) so y= 10
3 hours passed so y= 10 + 3*0.5 = 11.5 inches 
Grayson had 11.5 inches after three hours 
Assuming that the snow continued to fall for an unkhown time t 
y = 0.5*t + 10
we had 10 at the beginning so we add 10 (+10) 
the snow is growing by 0.5 inches in the single hour so we multiply by 0.5
t is the time and it can 4, 5, 6 ...... hours 
Just like a function :
- 0.5 is the slope 
- t is the variable 
- 10 is the y-intercept

You decide if it has a pattern if it is a repeating pattern then it is a rational number decimal however if it a decimal with no pattern it is irrational
