The term equation of straight lines is considered as the consideration of a certain unit, in this respect the equation can take part into various forms. In this perception, there are consideration of different points in a line if x-axes is taken and add any value on x-axes and the add the value 2, the correspondence value of y-axes shall be 0 + 2 = 2, 1 + 2 = 3, 2 + 2 = 4. Basically, it gives the relation between the coordinate points that are described in the straight lines. The two intersecting slopes, such as y = mx + c and ax + by = c.

Discussion 

Properties of ‘Equation of Straight Line’

• There is consideration of equations of straight-line formula such as A (x1, y1) and  B (x2, y2) are considered as the two points and at the particular time when both are connected with each other in this respect, both lines are extended to infinity.  In this context, the standard forms of linear equations with variables is established with the equation of ax + by = c
• The equation of straight lines are divided into three contexts such as standard form, slope-intercept form and point-slope form, both have different equations depending on the straight lines such as ax + by = c, y=mx+c and y-y1=m(x-x1), 
• The equations of lines through the provided lines are considered with the origin of the governing gradient, where y=x are centralised when every point of the line is equal to the x and y-axes. In this respect, the ingredients are found with certain formulas such as m = y2 − y1/ x2 − x1. In the same context substituting two sets of values is discussed with the equation of m = 1 − 0 /1 − 0 = 1
• The concept of the y-intercept in a line is considered as the y = mx + c equation. It is considered slightly different from other equations of straight lines. In this equation, x=0 is established by the K value of the coordinate axes.
• The standard form of the equation of lines is established as Ax+By=C, in this equation, A stands for integer, x stands for x-intercept, on the other hand, b represents another integer and y stands for the y-intercept. C is the outcome of this intercept. 
• The point-slope form of equations of straight lines is considered as the y – y1 = m (x – x1) formula. In this formula, the X and Y stand for the arbitrary point of these lines. This equation of straight lines is considered for m slope and it possesses through the point (x1, y1) it is found to use the point-slope form. 

Types of “equations of straight lines”

In this formation the general equations of straight lines such as y = mx + c. In some other consent, the substitute formula of m is established with considerable equations such as y = 1 /3 x + c. while concentrating on two different given points, the equation of a straight line is considered as m = (y2 − y1)/(x2 − x1). In this context the gradients of the lines are unknown. This should be an imaginary context where if ⅔ is considered as the gradient of a line, then the equation of this line shall be considered as y – y1 = m (x – x1).

Difference between the “standard form, slope-intercept form and point-slope form of straight-line”

The difference is established in the certain aspects where the different perspectives of straight  lines are intersected by the different forms of equalisation. In this perspective, there are considerations of standard form, point-slope form and slope-intercept form. In the standard form of the equation of straight lines ax + by = c is considered as the considerable equation which is used to make understanding regarding the equation of straight lines. If the equation is transformed by y = 2x – 1, 2x shall be subtracted from both sides of the equation and the formula shall be considered as y – 2x = 2x – 1 – 2x. 

Examples of “equation of straight lines”    

Finding the equation of a line where the slope is 5 and y-intercept is 3, in this respect the solution shall be m=5, and the y-intercept is b=3, the equation will be y=5x+3

Conclusion 

It can be concluded that the simplest form of a straight line. The equation of straight lines in point-slope form is considered, where the slope is m and it passes  through the point of (x1, y1). It is found to be using the point-slope form of the equation of straight lines, where the equation of point-slope form is considered as y – y1 = m (x – x1) in this respect the x and y is an arbitrary point present in a line.
