A straight line graph of a function y = mx + b, on the x,y plan is called the slopeintercept form. It is also known as yintercept form. In the slopeintercept form, y = mx + b, m is the slope and b gives the yintercept. Plug in the value of slope and the yintercept into this calculator. The slope intercept form calculator will give the equation of a line. 
Step 2 : Substitute the slope and yintercept value into the slope intercept form formula,
y = mx + b,
and get the equation of the line. Some of the problems are given below based on slope intercept form.
Solved Examples
Question 1: Find the equation of line with slope of 3 and yintercept 5.
Solution:
Step 1 : Given :
slope, m = 3
yintercept, b = 5
Step 2 : Equation of line,
y = mx + b,
y = (3)x + 5,
y = 3x + 5.
Solution:
Step 1 : Given :
slope, m = 3
yintercept, b = 5
Step 2 : Equation of line,
y = mx + b,
y = (3)x + 5,
y = 3x + 5.
Question 2: Find the equation of line with slope of 2 and yintercept 1.
Solution:
Step 1 : Given :
slope, m = 2
yintercept, b = 1
Step 2 : Equation of line,
