The students worked 45 hours i in a garden. there are 20 students in the class each student worked the same number of hours. how many hours did each student work in the gardens

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

it has the same slope and a different y-intercept

hope this : )
