( Coordinate geometry )
Coordinate geometry is a branch of mathematics that deals with the study of geometric figures and equations of curves by using coordinates. It allows one to find the geometric properties of points, lines, planes, and curves in two-dimensional or three-dimensional space. Coordinate geometry is used to solve real-world problems in fields such as engineering, physics, and architecture.
The coordinate plane is the foundation of coordinate geometry. It is composed of two perpendicular number lines, the x-axis (horizontal) and the y-axis (vertical). These axes are used to locate points in the plane. Points are written as (x,y) where x is the x-coordinate and y is the y-coordinate.
In coordinate geometry, lines are written in terms of an equation that states how x and y are related. The equations of lines can be written in two forms: the slope-intercept form and the point-slope form. The slope-intercept form is written in the form y = mx + b, where m is the slope and b is the y-intercept. The point-slope form is written in the form y - y1 = m(x - x1), where m is the
