Because the data points are generally not all in line with each other. If you connect the dots,
from one data point to the next and then to the next, you usually get a zig-zag line of many
segments, where the slopes of the segments are all different and cover a wide range. It would
be impossible to decide what the "real" slope of the data is. The "best fit" line is a line that finds
the pattern buried in the zig-zag data, giving each data point its best share of determining the best
single equation to represent the whole batch of points. That's why it's called "best".
which of the following examples best describes using an inclinied plane
- Me (:
vesseles
Im guessing that this is a distance over time graph. if so, the gradient of the line of best fit would have a low value. (not be very steep)
If it's laid properly, it can be. Then again...you get a guy who uses the best resins, and the best fiberglass, and he can give you a stronger composite using fiberglass than an inexperienced person using carbon fiber.
In my opinion a point is just a point on a graph A line is two points or more points with a certain slope
There are many ways, but probably you aren't in a statistics class, but in an algebra class. Step 1 plot all the data points on a coordinate plane graph (x-y graph) Step 2 estimate a line 'close' to points. Step 3 use 2 points ON THE LINE (these do not need to be data points) Step 4 find slope of line using points from step 3 Step 5 use point-slope formula to write the equation.
Yes
Suppose you have a sample of n points for two variables: (x1, y1), (x2, y2), ... (xn, yn). Without going into various statistical considerations (which are nonetheless important) you can estimate the slope of the 'best' line that can be used to estimate the values of y from the values of x using for formula given for beta-hat in the wikipedia article for simple linear regression.
You find two perfect points (exactly on a point) and use the formula y2-y1 over x2-x1
If choice B is supposed to be slope instead of slop, then B is the correct answer to describe the term gradient.

Draw a line of best fit through the plotted points which will give the y intercept. Draw a right angle triangle under the line which will be the triangles hypotenuse. Divide the vertical units of the triangle by the horizontal units which will give the value of the slope.
The slope of a vertical line would be parallel to the y axis.
well nobody is actually the best its all about you using your bending point wisely so if you use your bending points good you can be the best no promises though
consensus building
Plant, especially hardwoods and evergreens. Eliminate slopes using berms or laddering the slope, a step-down type of slope using steel reinforced rock to support each level, have an engineer or landscape designer advise you on best approach. Install french drain to provide a path for runoff.
