Mrs. Jacobson asked her students to write a word problem that describes the graph below.

A graph has days on the x-axis and money on the y-axis. A line goes through points (0, 8) and (4, 0).

Which word problem accurately describes the graph?
Jamie has $8, and she pays $2 per day to ride the bus.
Melinda has $4 and earns $2 allowance per day doing chores.
Carrina has $8, and she earns $2 per day babysitting.
Louise has $4, and she pays $2 per day for school lunch.

b is the correct answer

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
