Answer:
y = -1/2(x -2)
or
y - 4 = -1/2(x + 6)
Step-by-step explanation:
- Point-slope form: y - y1 = m(x - x1)
For point-slope form, you need two things:
- A point (x1, y1)
- The slope (m)
Given:
You already have at least one point, but you still need to find the slope.
To find the slope (m), use the formula: m = y2 - y1/x2 - x1
- Select which point is your (x2, y2) and which is your (x1, y1)
- NOTE: It doesn't matter which one you pick as long as you don't "mix-and-match" your x and y-coordinates
- For example: you can't choose (-6,0) for a point.
I've chosen:
- (x2, y2) = (2, 0)
- (x1, y1) = (-6, 4)
Plug in the info into m = y2 - y1/x2 - x1:
- m = 0 - 4/2 -(-6) = -4/2 + 6 = -4/8
- Simplify: -4/8 = -1/2
- m = -1/2
Now plug in the slope and ONE of the points into point-slope form
- Tip: It doesn't matter which point you choose but I'd recommend choosing the point with all positive numbers, if you can, to prevent the confusion of double negatives:
Answers could be:
- y = -1/2(x -2)
- y - 4 = -1/2(x + 6)
Answer:
x-axis
Step-by-step explanation:
A slope of zero means a line is a horizontal line. This would be parallel to the x-axis, since it runs horizontally.
Answer:
2009 data set is most homogeneous
Step-by-step explanation:
As per coefficient of variation, which is around 5% for the year 2009 and around 20% for the year 2010 we can state that the data set for the year 2009 is most homogeneous
Homogeneous means similar, it can be observed on the graph as well that the data for the year 2009 is less variant
Hope it answers your question.
