Pt Slope Formula
You may already be familiar with the ' y=mx+b ' form (called the slope-intercept form of the equation of a line). It is the same equation, in a different form! The 'b' value (called the y-intercept) is where the line crosses the y-axis. So point (x1, y1) is actually at (0, b). Two Point form Formula. Where, X1, X2 = X Axis Points Y1, Y2 = Y Axis Points X, Y = Axis Equation of a straight line can be calculated using various methods such as slope intercept form, point slope form and two point slope form. Slope Formula: The equation of the line through point A(xA, yA) A (x A, y A) with the slope m is determined by the formula y − yA = m(x − xA) y − y A = m (x − x A) Define What is the Slope of Line? In the previous lesson, we saw the slope-intercept form for straight lines. The other format for straight-line equations is called the 'point-slope' form. For this one, they give you a point (x1, y1) and a slope m, and have you plug it into this formula: y – y1 = m (x – x1). Based on the point and the slope provided for each question, apply point-slope formula to find the equation of a line and express the equation in slope-intercept form: y = mx + b. This level of worksheets features coordinates in the form of integers, and the slope provided can either be an integer or a fraction.
To calculate equation of a straight line, please enter the line coordinates (x1Pt Slope Formula Sheet
, y1) in the XY plane are used and Enter Slope Value (m).
The point slope form is defined that the difference in the y-axis coordinate between two points (y - y1) on a line is proportional to the difference in the x-axis coordinate points (x - x1
) and the proportionality constant m is the point slope of the straight line. The equation of a straight line can be found using following formula: y – y1 = m(x – x1)

Point of Intersection Formula
Have you heard of point of intersection concept in mathematics? If no, don’t panic. Here, we will discuss the point of intersection in detail and how to calculate it either graphically or algebraically. Also, the formula is applicable to a variety of areas like businesses, finance, study, construction, or physics etc.
Have you ever noticed the traffic signal on a road? This is the example of point of intersection that will appear at the point when two roads are meeting up at a point. In mathematics, point of intersection is the point where two lines or curves generally meet.The value of two curves would be same significantly and it can be used at multiple places.
Take another example, if we wanted to represent the revenue of a Company against the costs then point of intersection would define the situation where revenue and costs are significantly the same. Most of the times, this is the breakeven point for a Company. The point can be calculated either graphically or algebraically.
Draw the graph of two equations and see where they will intersect visually. This is not a tough job but can be completed quickly with a deep understanding and practice. In most of the examples, you could analyze that graph is the best technique to find the point of intersection with accuracy.
Sometimes, there are the situation when this is not possible to find the point of intersection graphically then how can you solve the equation. The answer is you can do it algebraically. Solve the equations find the values of x coordinated that would point of intersection for both the equations.
Point Gradient Formula
For a line, the ratio of vertical change to the horizontal change is defined through a point i.e. named as the point of gradient or we can name it as the derivative as well. In brief, the gradient of a line will be rise divided by the run – rise/run. If m is the gradient point across a line then point gradient formula in mathematics could be given as –
[large Point;Gradient =frac{y-y_{1}}{x-x_{1}}]
Point Slope Form Formula
The other popular format for straight line equations is point slope formula. For this purpose, you need to find out the values (x1, y1) and a slope m. Further, plug the values into the formula –
[large y-y_{1}=m(x-x_{1})]
Point Slope Formula Definition
Where,
m is the slope of the line.
x1 is the co-ordinates of x-axis.
y1 is the co-ordinates of y-axis.

Don’t scare of subscripts but they are just intended to indicate the points given to you. If you have the generic values for x and y coordinates then it can be directly plugged into the formula to calculate the final output. If you will calculate the values calculated from the slope-intercept form and the point slope form then they are exactly the same.
So, this is your choice which method are you planning to use and which technique suits you the most. Practice the technique and apply it as per your convenience for next mathematics problem.
