the answer
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
If you translate (move without rotation) a copy of the line towards the curve, the first point where the line touches the curve (the tangent to the curve with the slope of the original line) will be the point on the curve closest to the line. Draw a connecting line from this tangent point to the original line, intersecting that original line at right angles. Measure the connecting segment. It is the shortest distance. Vector analysis will give a mathematically strict solution, I do not have the ability to explain this in sufficient detail.
A chord is a line segment between two points on a given curve. Basically it's two points that are connected with a line which all happens to be on a curve. Most likely a circle
There is no such thing as a general pattern. Depending on the variables and the relationship between them, you can have points all over the plot, exactly on a straight line or a curve, or close to such a line or curve.

budget line shows purchasing power of an consumer but indifference curve show willingness of consumer for two commodities.
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.
one is straight and one is curved simple
A line along which the cost of something -- usually a combination of two factors of production -- is constant. Since these are usually drawn for given prices, which are therefore constant along the line, an isocost line is usually a straight line, with slope equal to the ratio of the (factor) prices.
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
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.
Actual distance traveled refers to the total distance covered between two points, taking into account any curves, turns, or detours in the route. Straight line distance, on the other hand, is the shortest distance between two points, ignoring any obstacles or changes in direction that may affect the path taken.
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.
