Ming wonders if there is a relationship between students' practicing music and their average in math class. She surveys ten of her classmates and asks them their average in math. She
also asks if they sing or play a musical instrument, and if so, how many hours they practice
per week. The scatter plot shows her results. Which statement is true?

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.
