Answer:

A The information in the table has a constant rate of change of 3.5.

Step-by-step explanation:

A linear equation is in the form y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change (slope) and b is the value of y when x = 0.

Let y represent the cost of a corsage and x represent the number of flowers in the corsage

The table (x, y) has the points (2, 7) and (3, 10.5). The equation is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-7=\frac{10.5-7}{3-2}(x-2)\\\\y-7=3.5(x-2)\\\\y-7=3.5x-7\\\\y=3.5x[/tex]

Therefore the rate of change is 3.5
