HELP plz!!!
This table represents the boiling point of water at different altitudes. Which equation represents water’s boiling point (y) based on the change in altitude (x)?

Altitude
(thousands of feet) Boiling Point of Water
(Fahrenheit)
(sea level) 0 212
0.5 211.1
1.0 210
2.0 208.4
2.5 207.5
3.0 206.6
4.0 204.8
4.5 203.9



A. -0.6x + 212
B. -1.8x + 212
C. -0.6x + 203.9
D. -1.8x

HELP plz

Answer 1

which altitude would you like to pick?

Answer 2

any

Answer 3

let's pick 1.0 or just 1

Answer 4

so x = 1

Answer 5

now let's plug this x value into each equation to see which one gives the result of 210

Answer 6

choice A

y = -0.6x + 212

y = -0.6*1 + 212

y = 211.4

So choice A is NOT the answer

Answer 7

choice B

y = -1.8x + 212

y = -1.8*1 + 212

y = 210.2

choice B is NOT the answer

Answer 8

see how this all works?

Answer 9

yes sir

Answer 10
