There seems to be no point in drawing endless graphs and using different alphabets so that you risk ending up spending a lot of time wondering how to use your knowledge in real life. The good news is that you can find many tips and sources, including peer reviewed articleswhich will help you do your geometry homework successfully and get higher grades. Use them and you will understand that this discipline is quite easy and can be mastered with interesting mind games and enough practice.

To avoid this vicious circle certain concepts must be taken as primitive concepts; terms which are given no definition. When the line concept is a primitive, the behaviour and properties of lines are dictated by the axioms which they must satisfy. In a non-axiomatic or simplified axiomatic treatment of geometry, the concept of a primitive notion may be too abstract to be dealt with.

In this circumstance it is possible that a description or mental image of a primitive notion is provided to give a foundation to build the notion on which would formally be based on the unstated axioms. Descriptions of this type may be referred to, by some authors, as definitions in this informal style of presentation.

These are not true definitions and could not be used in formal proofs of statements. The "definition" of line in Euclid's Elements falls into this category. In Euclidean geometry[ edit ] See also: Euclidean geometry When geometry was first formalised by Euclid in the Elementshe defined a general line straight or curved to be "breadthless length" with a straight line being a line "which lies evenly with the points on itself".

In fact, Euclid did not use these definitions in this work and probably included them just to make it clear to the reader what was being discussed.

In modern geometry, a line is simply taken as an undefined object with properties given by axioms[6] but is sometimes defined as a set of points obeying a linear relationship when some other fundamental concept is left undefined. In an axiomatic formulation of Euclidean geometry, such as that of Hilbert Euclid's original axioms contained various flaws which have been corrected by modern mathematicians[7] a line is stated to have certain properties which relate it to other lines and points.

For example, for any two distinct points, there is a unique line containing them, and any two distinct lines intersect in at most one point.

In higher dimensions, two lines that do not intersect are parallel if they are contained in a planeor skew if they are not.

Any collection of finitely many lines partitions the plane into convex polygons possibly unbounded ; this partition is known as an arrangement of lines. On the Cartesian plane[ edit ] Lines in a Cartesian plane or, more generally, in affine coordinatescan be described algebraically by linear equations.

In two dimensionsthe equation for non-vertical lines is often given in the slope-intercept form:write an equation in point-slope form for the line that passes through (0,-2), (3,2). Then use the same set of points to write the equation in standard form and again in slope-intercept form.

Writing Equations of Lines in Point-Slope Form Given a point on a line and the slope of the line, you can write an equation of the line. Consider the line that passes through (2, 3) and has a slope of 1—.

Get an answer for 'Write an equation in point slope form of the line that passes through the point (-7, 6) and has a slope of m=0.' and find homework help for other Math questions at eNotes. Watch video · So very quickly, you could use this information and your knowledge of point-slope form to write this in this form.

You would just say, well, an equation that contains this point and has this slope would be y minus b, which is y minus the y-coordinate of the point that this line contains-- is equal to my slope times x minus the x-coordinate.

Objectives: 1.

to write the equation of a line using the point-slope form of a line. 2. to understand and be able to explain the different part of the point-slope equation.

Write the equation of the line that passes through point (5, 4) with a slope of 0. would this be x=5 then? no x=5 is the equation of the vertical line passing through (5,4) Any horizontal line, (slope=0), has an equation of the form y = b notice that this.
