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 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 does a negative slope tell you about a line?
That it descends.
How can you tell which is positive and which is negative by numbers?
the number that has the minus sign in front of it is negative and the normal number is positive example: negative: -9 positive: 9
How do you trace a curve in differential calculus?
To trace a curve using differential calculus, you use the fact that the first derivative of the function is the slope of the curve, and the second derivative is the slope of the first derivative. What this means is that the zeros (roots) of the first derivative give the extrema (max or min) or an inflection point of the function. Evaluating the first derivative function at either side of the zero will tell you whether it is a min/max or inflection point (i.e. if the first derivative is negative on the left of the zero and positive on the right, then the curve has a negative slope, then a min, then a positive slope). The second derivative will tell you if the curve is concave up or concave down by evaluating if the second derivative function is positive or negative before and after extrema.

Can a position time graph tell in which directionthe displacement of an object is?
Yes, a position-time graph can tell you the direction of the displacement of an object. If the slope of the graph is positive, the object is moving in the positive direction. If the slope is negative, the object is moving in the negative direction.
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 does this tell you about the change in the velocity of the cart?
The positive slope of the velocity-time graph indicates that the cart is accelerating. The steeper the slope, the greater the acceleration. If the slope is negative, it indicates the cart is decelerating.
What does the slope of the tangent to the curve on a velocity-time graph measure?
The slope of the tangent to the curve on a velocity-time graph represents the acceleration of an object. Positive slope indicates acceleration in the positive direction, negative slope indicates acceleration in the negative direction, and zero slope indicates constant velocity.
What does a negative slope tell you about a line?
That it descends.
How can you tell if a graphed line with no numbers is positive or negative?
if the line slants down (from left to right) then it is negative. if the line slants up (from left to right) then it is positive. horisontal lines have a slope of "0" and and vertical ones are undefined.
How can you tell if a slope is negative?
if its going down from left to right it is a negative
On a distance time graph how can you tell which object is moving?
You can tell which object is moving by looking at the slope of the graph. A steeper slope indicates a faster-moving object, while a flatter slope indicates a slower-moving object. Additionally, a positive slope indicates forward motion, while a negative slope indicates backward motion.
How can you tell from a linear equation which direction it goes without graphing the equation?
You must find the slope, if it is positive, then the line is always increasing. If it is negative, then the line is always decreasing.
Without graphing how can you tell which slope is steeper?
For a positive number, as the slope(y=mx+b where m is the slope) gets greater in value, the line gets steeper when plotted on a graph. For a negative number, as the slope(y=mx+b where m is the slope) gets greater in value, the line gets less steep when plotted on a graph.
How can you tell which is positive and which is negative by numbers?
the number that has the minus sign in front of it is negative and the normal number is positive example: negative: -9 positive: 9
