In the two graphs below, you can see the same function, only described with two different forms of a linear equation: Y - b = m * (x - 0), which is the same as y = m * x + b. If you choose this point - (0, b), as a point that you want to use in the point-slope form of the equation, you will get: A straight line intercepts the y-axis in a point (0, b). The truth is that this is nothing else than a more precise point-slope form. The more popular is the slope intercept form: x 1, y 1 are the coordinates of a point, andĭo you see the similarity to the slope formula? What you might not know is that it's not the only way to form a line equation.Point-slope form is a form of a linear equation, where there are three characteristic numbers - two coordinates of a point on the line, and the slope of the line. See more information about triangles or more details on solving triangles.There is more than one way to form an equation of a straight line. Look also at our friend's collection of math problems and questions: Determine the coordinates of points B, C, and D so that ABCD is a square and S is the intersection of their diagonals. The rectangular coordinate system has a point A and a point S. If the midpoint of the segment is (6,3) and the other end is (8,4), what is the coordinate of the other end?ĭetermine the unknown coordinate of the vector so that the vectors are collinear: e = (7, -2), f = (-2, f2) c = (-3/7, c2), d = (- 4.0)

Write all the points on circle I with center O and radius r=5 cm, whose coo Write all the points that lie on a circle k and whose coordinates are integers. The Cartesian coordinate system with the origin O is a sketched circle k /center O radius r=2 cm/. If the midpoint of a segment is (6,3) and the other endpoint is (8,-4), what is the coordinate of the other end? A(-8, 6) B(-8, -6) C(8, -6) D(8, 6)įind the intersections of the function plot with coordinate axes: f (x): y = x + 3/5 Which point is located in Quadrant IV? A coordinate plane.

x + 3 with the x-axis, and C is the intersection of the graph of this function wįind the equation of the circle inscribed in the rhombus ABCD where A, B, and C.

What is the slope of the line segment?ĭetermine the coordinate of a vector u=CD if C(19 -7) and D(-16 -5)įind the perimeter of triangle ABC, where point A is the beginning of the coordinate system, and point B is the intersection of the graph of the linear function f: y = - 3/4 The segment passes through the point ( 5,2). What is the length, in units, of vector HI?įind the area of the triangle given by line -7x+7y+63=0 and coordinate axes x and y.ĭetermine the area of a triangle given by line 7x+8y-69=0 and coordinate axes x and y.Ī line segment has its ends on the coordinate axes and forms with them a triangle of area equal to 36 square units. the said problem should be used the concepts of: distance from a point to a liĪ triangle has vertices on a coordinate grid at H(-2,7), I(4,7), and J(4,-9). The calculation continues of the unknown parameters of the triangle using the identical procedure as in the SSS triangle calculator.Ĭonstruct an analytical geometry problem where it is asked to find the vertices of a triangle ABC: the vertices of this triangle must be the points A (1,7) B (-5,1) C (5, -11). The calculator uses the following solutions steps: From the three pairs of points, calculate lengths of sides of the triangle using the Pythagorean theorem. It uses Heron's formula and trigonometric functions to calculate a given triangle's area and other properties.

The calculator finds an area of triangle in coordinate geometry. The calculator solves the triangle specified by coordinates of three vertices in the plane (or in 3D space).
