The table shows the height of water in a pool as it is being filled. the slope of the line through the points is 2. which statement describes how the slope relates to the height of the water in the pool?

The slope is the rate at which water fills the pool.

Step-by-step explanation:

Another term for slope is "rate of change."  It describes the change in the dependent variable as the independent variable increases.

We are told the slope is 2; this means that the dependent variable rises 2 for every change in the independent variable.

In the situation of filling a pool with water, the measurements we would have would be the amount of water in the pool to begin with; the amount we end up with in the pool; and the rate at which the water level changes.  The only of these 3 that is a rate is the rate at which the water level changes; this must be the slope.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
