Answer:

A, C, E

Step-by-step explanation:

From the table you can see that the water depth cahnges

$0.8-0.4=1.2-0.8=1.6-1.2=2.0-1.6=0.4\ in$

for every

$4-2=6-4=8-6=10-8=2\ in$ of snow (option B is false).

This means that the function modelling this situation is linear function (option A is true and option D is false). Let the equation of this function be $y=ax+b.$ Then

$0.4=2a+b,\\ \\0.8=4a+b.$

Subtract these two equations:

$2a=0.8-0.4,\\ \\2a=0.4,\\ \\a=0.2.$

Hence,

$b=0.4-2\cdot 0.2=0.$

The equation of the straight line (the graph of linear function) is $y=0.2x.$ (option E is true) This line passes through the point (0,0), because its coordinates satisfy the equation (option C is true).
