Answer:

B. y = x - 12

Step-by-step explanation:

First, find the <em>rate of change</em> [<em>slope</em>]:

\frac{-y_1 + y_2}{-x_1 + x_2} = m

\frac{5 - 9}{-7 + 3} = \frac{-4}{-4} = 1

Then use the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done faster that way. It does not matter which ordered pair you choose:

−9 = 3 + b

−12 = b

y = x - 12

________________________________________________________________________________________________

−5 = 7 + b

−12 = b

y = x - 12

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.

Which exponential model best represents the data? O f(x) = 3(1.2) O f(x) = 2(0.3)* O f(x) = 2(3)* O f(x) = 3(0.2)*​
aleksley [76]

The exponential model has an initial value of 3

The exponential model of the data is f(x) = 3 * (1.2)^x

<h3>How to determine  the exponential model?</h3>

From the complete question,we have the following parameters:

  • Initial value, a = 3
  • Growth rate, r = 0.2

The exponential model is then calculated as:

f(x) = a * (1 + r)^x

Substitute known values

f(x) = 3 * (1 + 0.2)^x

Evaluate the sum

f(x) = 3 * (1.2)^x

Hence, the exponential model of the data is f(x) = 3 * (1.2)^x
