A middle school has sixth grade, seventh grade, and eighth grade students. There are 136 sixth graders and 119 seventh graders. The probability of selecting an eighth grader randomly from all of the students is 0.25 . How many students at this school are eighth graders?

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.
