What does a positive and a negative gradient look like?
A positive gradient goes uphill from left to right A negative gradient goes downhill from left to right
When the coefficient of x is positive the line what?
Has a positive gradient (in a y=mx+c graph)
How want to know that the gradient of a curve in displacement-time graph is increasing or decreasing?
If the gradient is a positive number the curve is increasing, and if the gradient is a negative number it is decreasing.
Does the line of best fit always have a positive gradient?
dunnno dunnno
What is significance of correlation?
it shows any pattern that may emerge in any given set of date, this includes a positive or negative correlation. positive where a gradient goes from low to high negative where a gradient goes from high to low

If the gradient is a positive number the curve is increasing, and if the gradient is a negative number it is decreasing.
How can you tell whether the gradient of a curve is increasing or decreasing?
Differentiate the curve twice and then enter a value for x. If the answer is positive, the gradient is increasing at that point. If the answer is negative, the gradient is decreasing at that point. And if the answer is zero, the gradient is not changing.

What is a positive linear relationship?
A linear relationship is one where your equation forms a straight line. A positive linear relationship is one where this line has a positive gradient.
Will the gradient of y equals -x plus 1 be positive or negative?
negative

What is a positive gradient in math?
A positive gradient is a characteristic of a function whose value increases as the value of the argument increases. So, if y is a function, f(x), of x, then an increase in the value of x is accompanied by an increase in the value of y.
What powers the proton gradient of positive ions in the stroma?
The proton gradient across the thylakoid membrane is powered by the flow of electrons from water to NADP+ during photosynthesis. This flow of electrons creates a proton gradient that drives ATP production through ATP synthase.
Does the line of best fit have to have a positive gradient?
Not at all. If the two variables have a negative correlation, that is as on increases the other decreases, then the line of best fit would have a negative gradient.
What is the gradient of acceleration time graph?
The gradient of an acceleration-time graph represents the rate at which the acceleration is changing over time. If the gradient is positive, it indicates an increase in acceleration, while a negative gradient indicates a decrease in acceleration. A horizontal line on the graph would represent a constant acceleration, where the gradient is zero.
