A random survey of 140 seventh graders from the various middle schools in a school district determined that 120 of them had a cell phone. Using the survey results, which is the best prediction for how many of the 1,500 seventh graders in the district have a cell phone?

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.

215.92 dollars is the answer
