Which one of these relationships is different than the other three? Explain how you know. Hint: Find all of the constants of proportionality.

Graph 2 has a different constant of proportionality

Step-by-step explanation:

See attachment for graphs

To calculate the constant of proportionality, we simply determine the slope of each graph using

Where x's and y's are corresponding values of x and y

Graph 1:

Substitute these values in:

Graph 2:

Substitute these values in:

Graph 3:

Substitute these values in:

Graph 4:

Substitute these values in:

From the calculations above, graph 2 has a different constant of proportionality of 5.5 while others have 5 as their constant of proportionality

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
