Stright Lines Math

A useful form is the point slope form or point gradient form.

Stright lines math. The general form of the equation of a straight line is a x b y c 0. Locus transformation of axes the straight line pair. The average slope of a line is a constant for the same line and is calculated as a ratio between the differences of y coordinates of two points the rise to that of x coordinates of those points the run. Inter first year 1a.

Functions mathematical inductions addition of vectors product of vectors and trigonometry. Equation of a straight line the equation of a straight line is usually written this way. They are identified with the symbol. The vertical bar is a glyph with various uses in mathematics computing and typography it has many names often related to particular meanings.

Find atleast two equations of the straight lines in the family of the lines y 5x b for which b and the x coordinate of the point of intersection of the lines with 3x 4y 6 are integers. Consider a line passing through two points a 1 b 1 and j k. Y y1 m x x1. When two straight lines intersect at 90 they are perpendicular identified with the symbol.

If two lines l 1 and l 2 are parallel then m 1 m 2. Pairs of straight lines can run parallel to one another never getting closer or further apart. Ideally the slope equation of a straight line is a linear function represented as y f x mx c. These are very simple to understand.

Y mx b or y mx c in the uk see below. K b 1 m j a 1. Straight lines can be alone or in pairs. Inter first year 1b.

Assume that the slope of the line passing through these points is m. Consider two lines l 1 and l 2 having the slopes m 1 and m 2 respectively. Take the records of the population and year graph given below. By using this find the population in the year 2005.

Pairs of straight lines can also intersect each other at any angle. You can t divide by zero. Sheffer stroke in logic verti bar vbar stick vertical line vertical slash bar pike or pipe and several variants on these names it is occasionally considered an allograph of broken bar see below. Straight up and down slope 3 0 undefined that last one is a bit tricky.

A line that goes straight across horizontal has a slope of zero. We use this form when we need to find the equation of a line passing through a point x1 y1 with slope m.
