Point Slope Form Calculator

Point slope form = y - y_{1} = m(x- x_{1})

The point slope form is defined that the difference in the y coordinate between two points (y - y1) on a line is proportional to the difference in the x coordinate points (x - x1). Enter values in point slope form calculator below to find the Equation of a straight line.Point-slope form is about having a single point and a direction and converting that between an algebraic equation and a graph.

Point slope form calculator is an online tool to find the general equation of line as ** Ax + By + C = 0. **All it needs is a slope

Point slope form and point slope intercept form both fulfil the same purpose of drawing a straight line equation. If you want to find out equation of line using slope intercept, you can use our slope intercept form calculator anytime.

The point slope form is defined as the difference in the ** y** coordinate between two points

It can also be stated as:

**“**The equation of a straight line in the form ** y − y_{1} = m(x − x_{1})** where m is the slope of the line and

The point slope formula can be expressed as:

**Point slope form = y - y _{1} = m(x- x_{1})**

**Where:**

*m*** refers to the slope of line,**

*x*** represents the coordinate on x-axis, and**

*y*** represents the coordinate on y-axis.**

Point-slope form is about having a single point and a direction and converting that between an algebraic equation and a graph. We can derive the slope of a line formula from the above point slope form equation.

**m = (y - y _{1}) / (x- x_{1})**

Point slope form can be calculated using the above point slope formula calculator. On the other hand, it can also be calculated using the formula for point slope form stated above. To find the point slope form manually, follow the steps below:

- Write down the coordinates for
,*x*_{1}and slope*y*_{1} - Write down the point slope formula.
- Substitute the values in the formula and calculate the equation of line.

**Solution:**

** Step 1:** Write down the coordinates for

*x _{1}* = -3,

slope

** Step 2:** Write down the point slope formula and apply that formula.

**y - y _{1} = m(x- x_{1})**

** Step 3:** Substitute the values in the formula and calculate the equation of line.

**y - 1 =2(x - (-3)) y - 1 = 2(x + 3) y - 1 = 2x + 6**

Therefore the Equation = 2x + 6 – y + 1

** Step 1:** Write down the coordinates for

*x _{1}* = 2,

slope

** Step 2:** Write down the point slope formula and apply that formula.

**y - y _{1} = m(x- x_{1})**

** Step 3:** Substitute the values in the formula and calculate the equation of line.

**y - 5 =-3(x - (2)) y - 5 = -3(x - 2) y - 5 = -3x + 6**

Example - point-slope form

Find the equation of the line that passes through (-3, 1) with slope of 2.

x1 = -3,

y1 = 1 and

slope m = 2.

__Apply Formula__:

y - y_{1} = m(x- x_{1})

y-1 =2(x-(-3))

y-1 = 2(x+3)

y-1 = 2x+6

Therefore the Equation = 2x+6-y+1

**Equation of the line = 2x-y+7**
