Given:

The graph of a trend line.

To find:

The equation of the trend line.

Solution:

From the given graph it is clear that the trend line passes through the points (0,4) and (9,7). So, the equation of the trend line is:

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-4=\dfrac{7-4}{9-0}(x-0)$

$y-4=\dfrac{3}{9}(x)$

$y=\dfrac{1}{3}x+4$

Therefore, the equation of the trend line is $y=\dfrac{1}{3}x+4$ .

Answer:

x = -10

Step-by-step explanation:

2(x + 1) - 10 = -28

2 * x = 2x

2 * 1 = 2

2x + 2 - 10 = -28

Combine like terms

-10 + 2 = -8

2x - 8 = -28

+8 +8

2x = -20

This is a theorem called Converse of Alternate Exterior Angles that states that <em>if two lines are cut by a transversal and the alternate exterior angles are congruent, then the lines are parallel</em>. Moreover, this theorem is based upon the corresponding Angles Converse Postulate that states that<em> if two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel. </em>We don't need to prove this postulate, it's assume to be true. So our goal is to get corresponding angles congruent in order to use the corresponding Angles Converse Postulate,
