Slope Intercept Form Calculator

Input the required parameters into the calculator and it will readily calculate the equation of the line in slope-intercept form.

The slope intercept form calculator finds the equation of the straight line based on the given two points, one point, or the intercept & slope data.  With it, you can also find the slope and y-intercept of any linear equation, enhancing precision and bringing clarity in your mathematical calculations.

What Is Slope Intercept Form?

The slope intercept form of the linear equation is y = mx + c that is constructed with y-intercept and slope of the line “m”. This form of the linear equations is known as the slope intercept form. The slope signifies the degree of incline or steepness of a line.

Slope Intercept Formula:

The formula that is used to find the slope intercept form equation is outlined below:

 y = mx+c

Where:

  • m = Slope of line 
  • x = x- coordinate of the line 
  • y = y-coordinate of the line 
  • c = y-intercept of the line 

The “m”  is the change in y and along with the x coordinates at any point of intersection of “x” and “y”

You can also find the x-intercept of a line with the help of the above formula. The x-intercept is the value of the x at which the line crosses the x-axis.

How To Find The Slope Intercept Form (Equation of A Straight Line)?

Follow the below mentioned example to find the equation of slope intercept:

Practical Example:

Find the slope intercept form of the line with a slope is “2” and the y-intercept “5”. Solution:

Step 1:

Slope of the line = m =  2 y-intercept = c = 5

Step 2:

The slope intercept form of linear equations is: 

y = mx+c

m = 2 and c = 5

⇒ y  = 2x +5

By putting the given values in slope intercept formula you will get the slope intercept form equation in which y = 2x + 5.

Also, consider this simple slope calculator that finds the slope of a line passing through the two given points. Keep in mind that all equations are not the same, some formulas describe curves that may never intercept the y-axis, the x-axis, or both of them.

Examples of Slope-Intercept Form:

In the following table, we have provided some examples so that you can easily understand how you can write the linear equations in slope intercept form.

Points(-2,-4) has a slope of 4

Answer

Slope intercept form y = 4x+4

Step-by-step solution:

y + 4 = 4 (x+2)

y + 4 = 4x+8

y = 4x+8-4

y = 4x+4

FAQ’s:

Is Slope Intercept Form The Same As Standard Form?

No, because they are two different ways of defining a straight line. 

  • Slope intercept form equation = y = mx +b
  • Standard form =  Ax + By + C = 0

How Do You Find The Slope Between Two Points?

To find the equation of a line having two points, follow the below-mentioned steps:

  • Determine the slope using the following formula, m = (y₂ - y₁) / (x₂ - x₁)
  • After that use the point-slope to get the equation of the straight line as below:
  • y - y₁ = m(x₂ - x₁).
