Question

Help me make this into a word problem?? Fan and medal

Answer 1

what do you need to do with y=-6x?

Answer 2

Make it into a word problem that makes sense

Answer 3

can you read it outloud?

Answer 4

I'm assuming the OP means something along the lines of "The contractors are trying to make a line that .... blah blah blah"?

Answer 5

Uh..

Answer 6

I just need it made into a word problem

Answer 7

How about something like this:


x = number of hours that have elapsed
y = depth of a submarine (y = 0 is at the sea level surface, negative y values represent when the submarine is below the water line)


If a submarine dives straight down at a rate of 6 mph, then after x hours, the depth of the submarine would be `y = -6x` miles


I'm using the idea that

Distance = Rate * Time

"rate" is another term for "speed"

Answer 8

Oh thank you! I didn't know where on earth to start! Thank you so so so so so so much!

Answer 9

Then you can ask questions like


a) what is the depth of the submarine after 3 hours? (plug in x = 3 to find out)


b) how many hours go by when the sub is 18 miles below the water level? (replace y with -18 and isolate x)
