ruler
Quadratic, simultaneous and straight line equations
pH is a logarithmic scale; because of the way calculus and maths works, graphing such a scale against a log results in a straight line.
A chord is a straight line joining any 2 points on the circumference of a circle
the bearing of something is the angle. for example there are 180 degrees on a straight line so the bearing of a straight line is 180 degrees. To work out the bearing of something though you need a protracter
You can draw straight lines with the help of a ruler or anything with a straight edge.
In maths, a ray.
It usually means a straight line going from one vertex of a polygon, polyhedron (or a shape in more dimensions) to another vertex. More generally any line between the 'X' or 'Y' axes on a graph
We use line number in maths subject.
In mathematics, when you have a sum represented above and below a straight line, it often indicates the concept of a definite integral or the area between curves. The straight line can represent a specific value or function, and the areas above and below the line signify the positive and negative contributions to the total sum. This visual representation helps in understanding the net area or total accumulation of values over a given interval.
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.
it is called asewing machine!
Yes. If it is not straight, then it is not a line.
