Please help me. I am doing an important assessment.

B. Samuel will pay 10 dollars less if he buys the boots from store a

Step-by-step explanation:

25% of 80 is 20 80-20 is $60 is he buys at store a

80-10 is $70 if he buys at store b

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
