Depends on your definition of "linear"
For someone taking basic math - algebra, trigonometry, etc - yes. Linear means "on the same line."
For a statistician/econometrician? No. "Linear" has nothing to do with lines. A "linear" model means that the terms of the model are additive. The "general linear model" has a probability density as a solution set, not a line...
No. A linear graph has the same slope anywhere.
how to find the slope of the line between the two points (-1,2) and (3, -6). can you plaese show how
To find the slope we need to divide the difference in rise between these two points by the difference in run between them. The difference in rise equals: 3-2 = 1. The difference in run between these points equals: 2-4 = -2.Now we just divide 1/-2 and we get the slope of the line formed by these two points: -0.5

Calculate the difference of the y-coordinates, and divide it by the difference of the x-coordinates. That is the slope.
To estimate linear relationships between variables.
No. If you have more than two points for a linear function any two points can be used to find the slope.
A linear relationship means that the slope of the line is proportional, which means that the line is straight. In contrast to the linear realtionship, the non-linear relationship's slope is not proportional and the line will curved and not straight. Formula of calculating the slope is the difference of y divided by the difference of x.
If the algebraic equation is linear, in the form y = mx + b, the slope is simply m; the difference in y of any 2 points divided by the difference in x of those points (rise over run). If the equation is non-linear, the slope is the first derivative of that equation, from calculus. You woul need to know calculus to solve in this case. The slope will vary from point to point, unlike the linear case, where slope is constant.
Two points don't have a slope. But the line between them does. The line between the points (-5, 3) and (3, 3) has a slope of zero.
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
To find the slope between two points: slope = change_in_y/change_in_x Thus for the points (4, 5) and (6, 8), the slope between them is given by: slope = (8-5)/(6-4) = 3/2 = 1½ = 1.5
Several factors can contribute to the uncertainty of the slope in linear regression analysis. These include the variability of the data points, the presence of outliers, the sample size, and the assumptions made about the relationship between the variables. Additionally, the presence of multicollinearity, heteroscedasticity, and measurement errors can also impact the accuracy of the slope estimate.
The slope of the speed/time graph is the magnitude (size) of the object's acceleration.
It's the gradient, or the steepness, of a linear function. It is represented by 'm' in the linear formula y=mx+b. To find the slope of a line, pick to points. The formula is (y2-y1)/(x2-x1). See the related link "Picture of a Linear Function for a picture of a linear function.
We define the rate of change between any two linear points as the slope, and designate it with the letter m. m = delta y over delta x.
To write a linear equation given two points, you can first calculate the slope using the formula: slope = (y2 - y1) / (x2 - x1). Once you have the slope, you can choose one of the points to substitute into the point-slope form of a linear equation: y - y1 = m(x - x1), where m is the slope and (x1, y1) is one of the points.
