raincoat, a hoodie, or a sweater. He will also wear
a baseball cap that is black, green, orange,
purple, or white. On separate paper, draw a tree
diagram that shows all possible combinations.
How many combinations are possible?

I'm not that smart and I don't know how to show you the tree but i'm pretty sure the answer is 15

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.
