A Carpenter is preparing to put a roof on a garage that is 20’ x 40’ x 20’. A steel support beam H equals 44 feet in length is positioned in the center of the garage. Do you support the roof, another beam will be attached to the top of the center beam. At what angle of elevation is the new beam? In other words, what is the pitch of the roof?

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.

what is the graph
