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:

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

X-intercept=2; containing the point (-5,4), using either the general form or the slope-intercept form of the equation of a line.
Rus_ich [418]
The line contains point (2, 0) and (-5, 4).
y - 0 = (4 - 0)/(-5 - 2) (x - 2)
y = -4/7 (x - 2)
7y = -4(x - 2)
7y = -4x + 8
4x + 7y = 8
