Class 11 Various forms of equations of a line

Class 11 Various forms of equations of a line- In mathematics, a line can be represented in various forms. The primary forms of the equation of a line are:

1. Slope-Intercept Form: The slope-intercept form of a line is given by: y=mx+b where m is the slope of the line, and b is the y-intercept (the point where the line crosses the y-axis).
2. Point-Slope Form: The point-slope form of a line with slope m and passing through the point (x1​,y1​) is given by: y−y1​=m(x−x1​)
3. Two-Point Form: If you have two points (x1​,y1​) and (x2​,y2​) on the line, the two-point form of the line is given by: y−y1​=x2​−x1​y2​−y1​​(x−x1​)
4. Slope-Point Form: If you know the slope m of the line and a point (x1​,y1​) on the line, you can write the equation as: y−y1​=m(x−x1​)
5. Intercept Form: The intercept form of a line is given by: ax​+by​=1 where a and b are the x- and y-intercepts of the line, respectively.
6. Normal Form: The normal form of a line is given by: Ax+By=C where A, B, and C are constants, and A and B are not both zero. This form is also known as the standard form.

These forms are equivalent, and you can convert between them as needed. The choice of which form to use depends on the information you have about the line and the context in which you are working. Each form has its advantages in different situations.
