1) A: The first table

2) B: The water level increases by 2 inches each hour.

Hope this helps

Answer:

Question 1). table 1

Question 2). Option B

Step-by-step explanation:

Question 1). If we analyse graph 1 we find a straight line of which we have to find the equation first.

Since the equation of any line is represented by y = mx + c

where m = slope of the line

c = y- intercept

Graph 1 shows line has no y-intercept (passing through origin) so c = 0

and the equation will be y = mx

Now slope m = [tex]\frac{y-y'}{x-x'}[/tex]

In graph 1 line is passing through two points (3, 1) and (0, 0).

Therefore m = [tex]\frac{1-0}{3-0}=\frac{1}{3}[/tex]

Finally equation of the line is [tex]y=\frac{1}{3}x[/tex]

or x - 3y = 0

Now we plug in the values of x and y from graph 2, table 1

For (-3, -1)

-3 - (3)(-1) = -3 + 3 = 0

So table 1 is the answer.

Question 2). In this question we have to describe the pattern showing the relation between x and y.

In other words we have to find the slope of the line which describes flow of water y in x hours.

Slope = [tex]\frac{y-y'}{x-x'}[/tex]

Here the line is passing through two points (0, 0) and (1, 2)

By putting the values in the formula of slope

[tex]m= \frac{2-0}{1-0}=2[/tex]

So water level in the cup is increasing by 2 inches per hour.

Option B. is the answer.
