Dr. stein bought 30 notebooks, 60 pencils and 300 erasers to make identical packages with some notebooks, some pencils and some erasers for his students. he used everything he bought, and every student got a package. what is the largest number of students dr. stein can have in his class?

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.
