Answer:
y = 9x + 175
Step-by-step explanation:
Choose one value for y in the table, for example, 211. All the equations have 9x, so multiply the corresponding x for 9:
9•4 = 36
Now make the value of y - 36:
211 - 36 = 175
Now you have the equation:
y = 9x +175
How do I calculate the ratio of a table? X values are: 40, 20, 15, 13, 13, 13, 13, 13, 13, 13, 13 Y values are: 0, 20, 25, 27, 2

First of all, you need to understand what you mean by "the ratio of a table."
The ratio of any y-vlaue to any corresponding x-value is not a constant here, so that is apparently not what you're talking about.
_____
When you plot the points on a graph, they are all on a straight line. That line has a slope of -1, which you can figure from the graph or from the table. Perhaps this is what you're asking.
Pick two (different) pairs of x- and y-values, for example, (x, y) = (40, 0) and (20, 20). Now, compute the difference in y-values and divide that by the difference in corresponding x-values.
... y-difference = (20 - 0) = 20
... x-difference = (20 - 40) = -20
Then the ratio of these is
... (y-difference)/(x-difference) = 20/-20 = -1

Answer:
Step-by-step explanation:
This equation is of the form y = kx, where k is the constant of variation. In our case, this is 2/5. One thing that separates a direct variation from simply a line (although a direct variation does in fact represent a line when graphed), is that the graph of a direct variation will ALWAYS go through the origin. That means that it will never have the "+ k" at the end of its equation and its y-intercept is always 0.
