(3 points)
a. The constant of proportionality is
.

b. Write an equation that represents this graph
.

c. This is a proportional relationship because the y-intercept is

15
0
30
1
(0,0)
(0,15)
(2,30)
y=15x
y=3/2x
y=x-15
y=x+15

Answer 1

To answer the questions based on the context provided (assuming the graph depicts a linear relationship), here is how you could proceed:

a. The constant of proportionality is **15**. (Assuming from the options given and a typical proportional relationship where the graph increases consistently.)

b. An equation that represents this graph is **y = 15x**. (This represents a direct proportionality where y increases 15 times for each unit increase in x.)

c. This is a proportional relationship because the y-intercept is **(0,0)**. (In a proportional relationship, the line always passes through the origin, indicating that when x is zero, y is also zero.)

Thus, the answers are:

a. 15
b. y = 15x
c. (0,0)
