Question

What is the slope of the trend line drawn into the scatter plot?

Answer 1

Formula for slope: $\frac{y2-y1}{x2-x1}$
Plug in points given: $\frac{136-27}{13-2} = \frac{109}{11} = 9.9 = 9 \frac{9}{10} (Rounded)$
Slope: $9.9 = 9 \frac{9}{10}$

Answer 2

Answer:

9.9 is the slope of the trend line drawn into the scatter plot

Step-by-step explanation:

Using slope formula:

$\text{Slope} =\frac{y_2-y_1}{x_2-x_1}$          ....[1]

As per the statement:

Consider two points from the given graph:

$(2, 27)$ and (13, 136)

Substitute in [1] we have;

$\text{Slope} =\frac{136-27}{13-2}$

⇒$\text{Slope} =\frac{109}{11}$

Simplify:

$\text{Slope} \approx 9.9$

Therefore, 9.9 is the slope of the trend line drawn into the scatter plot
