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 in point-slope form? (HINT: Give all fractions as decimals)

Answer 1

First of all- just to help yall out the verified person is incorrect.

The answer is-  y= -29= -7/2 (x-6)

i did the test. :)

Please mark me brainiest!

hope i helped

Answer 2

The slope - intercept form: y = m x + b
43 = 2 m  + b  ⇒   b = 43 - 2 m
36 = 4 m + b 
------------------------
36 = 4 m + 43 - 2 m
36 - 43 = 4 m - 2 m
- 7 = 2 m
m = - 7 : 2
m = - 3.5
b = 43 - 2 · ( - 3.5 ) = 43 + 7 = 50
Answer:
Yulian`s situation is represented by the equation:
y = - 3.5 x + 50
