Question

Yulian works at the zoo feeding the animals. He puts water in the elephant habitat at the beginning of the day. The table shows how much water, in gallons, remains at different times during the day.

What is the equation that represents Yulian’s situation?

(y – 29) = ___(x –___ )

Yulian’s Situation
Hours 2 4 6 8
Water remaining 43 36 29 22

Answer 1

point slope form equations are of the form \(y-y_1=m(x-x_1)\) where \((x_1,y_1)\) is a point the line goes through and m is the slope

Answer 2

i still don't understand... @bibby

Answer 3

sorry, the site has been acting up all day for me
(x1,y1) is one of the points the line or function goes through
for example a line with a slope of 5 that passes through (3,-6) would look like
\(y--6=5(x-3)\)
\(y+6=5(x-3)\)

Answer 4

so that's the answer?

Answer 5

no? I don't give answers, I give you the recipe

Answer 6

oh.. hahaha thanks

Answer 7

@bibby

Answer 8

it's easy to give you the answer
it's more rewarding to teach you /how/

Answer 9

yeah.. i know.. but i'm in the middle of a test and was hoping for a quick answer. @bibby

Answer 10

we can't help with tests.

the only help I can give is that slope = \(m=\large \frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}\)

Answer 11

im just not good at math... @bibby

Answer 12

I suck too. I still try sometimes

Answer 13

can i please have the answer? @bibby

Answer 14

ask nicely
wait damn
you said the magic word

Answer 15

you have 2 points (2,43) & (4,36)
plug that into the formula and find the slope

Answer 16

thx @bibby
