Please any help with this math problem

y = 1/4X + 1/2

Step-by-step explanation:

the formula of a line is y = aX + b

a = the slope, so a = 1/4. you get the following:

y = 1/4X + b

to find b we need to fill in the coordinates:

1/2 = 1/4 • 0 + b

b = 1/2

so the answer is:

y = 1/4X + 1/2

(2 1/2)  / (1/4)  = 10
in a real world    scenario;    say  you  have $2.50 and want to divide  into quarters -- how many quarters would you  have?
2.50  /.25  ==?
Another  example -- you  have 2 and a half pizzas you want to give each person at your party 1/4 pie.   Haw many pieces   can you get out of 2 1/2.
