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.
We use line number in maths subject.
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
it is called asewing machine!
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.
Yes. If it is not straight, then it is not a line.
For any line, there needs to be two points. If the line passes through points and extends in both directions forever, it's a line. If the line just goes between the two points, its called a line segment. If the line goes through both points but only extends in one direction, it's a ray.
