Which is an equation of a direct proportion? a.y=1/6x+6 b.y=6/x c.y=6x-6 d.y=6x
1 answer:
Answer:
Option D. y=6x
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
<em>Verify each case</em>
case a) y=(1/6)x+6
Is a linear equation, but is not a direct variation. The line not passes through the origin
case b) y=6/x
The equation represent an inverse variation
case c) y=6x-6
Is a linear equation, but is not a direct variation. The line not passes through the origin
case d) y=6x
The equation represent a direct variation

Step-by-step explanation:
A (-6, 5), B (-2, 4), <em>C (-2, 5) </em>
Form a triangle by adding a new point to the graph.
*in this case it is coordinate C
- First step: Find the distance between points A and C
From A to C there are 4 units.
- Second step: Find the distance between points B and C
From B to C there are 9 units
Next you need to use the pythagorean theorem to find the length of A to B
Now use the lengths you have to find the missing length.
