one is straight and one is curved simple
the answer
budget line shows purchasing power of an consumer but indifference curve show willingness of consumer for two commodities.
What is the difference between a trend line and a line of best fit
The tangent line is the instantaneous rate of change at a point on a curve. The secant line crosses a curve twice at points A and B, representing the average rate of change between those two points.
Linear is a straight line and non linear could be a curve or anything but a straight line
Between the two point line to say that is both a curve and there are clear.
If you take two distinct points on a curve, the arc is the part of the curve connecting the two points while the chord is the straight line connecting them.
Curvature :act of curving, state of being curved; measure of the degree of a curve in a line. Curve:line that is not straight, continuously bending line; bend, turn (in a road) Reference: babylon Dictionary
Regression techniques are used to find the best relationship between two or more variables. Here, best is defined according to some statistical criteria. The regression line is the straight line or curve based on this relationship. The relationship need not be a straight line - it could be a curve. For example, the regression between many common variables in physics will follow the "inverse square law".
A parabola refers to a symmetrical open plane curve that is formed by the intersection of the cone with a plane that is parallel to its side. The curve on the other hand refers to a line that gradually deviates from being straight for some or all of its length.
Tangent:In geometry, the tangent line (or simply the tangent) is a curve at a given point and is the straight line that "just touches" the curve at that point. As it passes through the point where the tangent line and the curve meet the tangent line is "going in the same direction" as the curve, and in this sense it is the best straight-line approximation to the curve at that point.Chord:A chord of a curve is a geometric line segment whose endpoints both lie on the outside of the circle.
Relationship between Lorenz curve and Gini coefficient is the more the Lorenz line curves away from the line of equality, the greater the degree of inequality represented.
