Last week, hazel paid $32 to have 50 reports printed. this week, she paid $57 to have 100 reports printed. assume the relationship is linear. which equation models the relationship between the number of reports, x, and the cost, y?

y = 2x + 68
y=1/2x+7
y=1/2x+34
y = 2x + 34

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.
