Kim's flower was 2 inches high when she got it. It grew 0.75 inches per month until it was 12 months old. She keeps track of her flower's growth on a coordinate grid by graphing its height every two months and connecting the points to show the growth in between months.

Choose the correct rule for the graph shown:
y = -2x + 3
y = 3/2x + 3
y = 2x + 1.5
y = -3/2x + 3/2
y = -2x + 3
y = 3/2x + 3
y = 2x + 1.5
y = -3/2x + 3/2

The statements that are true are:
1. The function is increasing over time, since the flower's height grows by 0.75 inches per month.
2. The function is continuous, since it is graphed by connecting the points of the flower's height every two months.
3. The function is nonlinear, since it does not have a constant growth rate (the growth rate changes with time).

The function that has the values of the range decrease as the values in the domain increase is:
f(x) = −2x + 15, since the coefficient of x is negative (-2), which means that as x increases, the overall value of the function decreases.

The given options do not identify the function. Therefore, the slope cannot be determined. Please provide the function to proceed further.

To find the rate of change of the price of bread, we need to divide the change in price by the number of years:
Change in price = $3.50 - $1.75 = $1.75
Number of years = 5
Rate of change of price = Change in price / Number of years
Rate of change of price = $1.75 / 5 = $0.35 per year
Therefore, the rate of change of the price of bread is $0.35 per year.
So the option is: $0.35 per year
Change in price = $3.50 - $1.75 = $1.75
Number of years = 5
Rate of change of price = Change in price / Number of years
Rate of change of price = $1.75 / 5 = $0.35 per year
Therefore, the rate of change of the price of bread is $0.35 per year.
So the option is: $0.35 per year

In the given model y = 0.40x + 45,000:
- x represents Bill's total sales for the year.
- 0.4 represents Bill's commission rate, in decimal form (i.e., he earns 40% of his total sales as commission).
- 45,000 represents Bill's base pay for the year.
Therefore, the meaning of the y-intercept in the model is that it represents Bill's base pay before commission.
- x represents Bill's total sales for the year.
- 0.4 represents Bill's commission rate, in decimal form (i.e., he earns 40% of his total sales as commission).
- 45,000 represents Bill's base pay for the year.
Therefore, the meaning of the y-intercept in the model is that it represents Bill's base pay before commission.
