Y = m x + b
2 = 6 m + b
-4 = 8 m + b /*(-1 )
---------------------------
2 = 6 m + b
+
4 = - 8 m - b
--------------------
6 = - 2 m
m = - 3
2 = 6 * ( - 3 ) + b
2 = - 18 + b
b = 20
The equation is:
y = - 3 x + 20 ( or in the other form: 3 x + y - 20 = 0 )
In two similar geometric figures, the ratio of their corresponding sides is called the scale factor<span>. To find the </span>scale factor<span>, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the </span>scale factor<span> from one figure to the other. say a triangle had points of A(-1,0),B(0,1),and C(1,0) and the scale factor is two you basically double all the points so the A' is (-2,0), B' is (0,2), and C' is (2,0).</span>

Answer:
An arrow diagram
Step-by-step explanation:
Helps keep track of intricate relationships between variables. Specifies the phenomena of interest: independent, alternative, antecedent and intervening.
-Time on the bottom with an arrow
-Antecedent -> Independent -> intervening-> dependent
An arrow diagram is defined as a process diagramming tool used to determine optimal sequence of events, and their inter-connectivity. It is a network diagramming technique in which activities are represented by arrow, used for scheduling and to determine the critical path through nodes. The arrow diagramming method shows the required order of tasks in a project or process, the best schedule for the entire project, and potential scheduling and resource problems and their solutions. The arrow diagram lets you calculate the "critical path" of the project the flow of critical steps where delays can affect the timing of the entire project and where addition of resources can speed up the project.
One headed arrow connecting two variables= "X directly causes Y"
