The electrostatic force of attraction between the oppositely charged ions is called the ionic bond or electrovalent bond. This bond is formed between two atoms whose electronegativity difference is large and they can attain octets by the complete transfer of one or more electrons from one atom to another. The atom which loses electrons is […]
In a chemical reaction, one or more substances, called reactants undergo a chemical change to produce new substances called products of the reaction. Thus a chemical reaction is a process in which reactants undergo a change to produce products. Reactants: One or more substances which react and undergo chemical change are called reactants of the […]
Science > Mathematics > Coordinate Geometry > Straight Lines > Equation of Line: Two Point Form In this article, we shall study to find the equation of a line using a two-point form. Example 01: Find the equation of a line passing through the points (5, 4) and (3, -2) Solution: Let the points be […]
Science > Mathematics > Coordinate Geometry > Straight Lines > Intercepts of Line on the Axes In this article, we shall study the concept of intercepts of line on coordinate axes. If a straight line intercepts X-axis at the point A and Y-axis at point B, then the x-coordinate of A and y-coordinate of B […]
In this article, we shall study to prove given quadrilateral to be or parallelogram, or rhombus, or square, or rectangle using slopes. Example – 01: Using slopes show that the points (-2, -1), (4, 0), (3, 3) and (-3, 2) are the vertices of a parallelogram. Solution: Let A(-2, -1), B(4, 0), C(3, 3) and […]
