How can you tell from a scatter plot wheather two variables have a positive correlation a negative correlation or no correlation?
Positive correlation = the slope of the scattered dots will rise from left to right (positive slope) Negative correlation = the slope of the scattered dots will fall from left to right (negative slope) No correlation = no real visible slope, the dots are too scattered to tell.
How do you tell wheater a slope is positive or negative?
A slope is positive or negative based on if the line goes from the upper left corner down to the lower right corner or right to left. Left is positive right is negative.
For a negative slope the rise is and the run is positive?
For a negative slope, the rise is negative and the run is positive.
How can you tell from a graph on a line what type of slope it has?
If the line slants up and to the right, it has a positive slope. If it is slanting up and to the left, it has a negative slope.
What is the difference between positve and negative correlation?
Positive correlation has a positive slope and negative correlation has a negative slope.

How do you know when the slope of a line is negative?
You know when the slope of a line is negative when m in the slope-intercept form equation y=mx+b is negative. For example, y=-3x+2 has a negative slope since m (which is -3 in this case) is negative. This is the same when finding a positive slope, because if m is positive, then the slope is positive.
Is a slope of a line always positive?
No because the slope of a line can be positive or negative
What will happen to the slope of a line if the line is shifted so that the y intercept increases and the x intercept remains the same?
The answer depends on the signs of the original intercepts.x negative, y negative: negative slope becomes less negative and could go positive.x negative, y positive: positive slope becomes greater.x positive, y negative: positive slope becomes less positive and could go negative.x positive, y positive: negative slope becomes more negative.For 1 and 3, the slope changes sign when the y intercept crosses the origin.
What are some Real examples for negative slope and positive slope?
A positive slope is simply a slope going upward on a graph from left to right. A negative slope is a slope going downward from left to right. Often, negative slopes are the reverse of positive slopes and are both depending on the person's direction.
For a negative slope what is the rise if the run is positive?
negative
What are four types of slope?
positive slope negative slope zero slope undefined
Can a position time graph tell in which directionthe displacement of an object is?
Yes. If the slope is positive, the direction of the displacement is positive (e.g. north, east, or right). If the slope is negative, the direction of the displacement is negative (e.g. south, west, or left).
