So this is essentially a proportion problem. They want you to be able to recognize a relationship between the two. The easiest way to go about this is to draw a picture (I have included one). What you want to do is notice that you are given both shadow lengths. This is essentially going to be your first step to creating the proportion.
Understanding that we know the shadow lengths, we can turn these into a fraction such as so:
4ft/20ft.
Now that we know that, we need to look at are unknown. Our unknown is the height of the utility pole. We can solve this by substituting for X since we know the utility worker is 5.5 ft tall.
Your fraction for that would look like:
5.5ft/X
Make sure to always make your top to top match, such as since I put the utility worker's shadow on top, I need to put his height on top.
Now we can solve.
4ft/20ft =5.5ft/X
We need to cross multiply to get an equation we can work with. If we cross multiply, Your equation will look like:
4x = 110ft
This is a simple one step equation. Divide both sides by 4 to get your answer.
x= 27.5ft.
This means your Utility pole's height is 27.5ft.
Answer:
See attachment for graph
Or
The slope intercept form is
Step-by-step explanation:
Assuming you want to graph the straight line given in point-slope form as
Then we need at least two points on this line
When we compare to the point-slope formula then we obtain (-5,-2) as a point on this line so we plot it.
When x=0, y=4(0+5)-2=18 so we plot (0,18)
We then draw a straight line through as shown in the attachment.
On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:
