# Slope Intercept form Calculator

Find the equation in slope-intercept form required to enter the value of slope(m) and value of y-axis-intercept(b) means where the line crossing the y-axis.

**To Calculate Equation of a straight line using formula:**

y = mx + b

y = mx + b

Slope(m) | |

y - intercept(b) | |

Equation: | |

In other words we can say to find the y-intercept we can set x-axis value to zero (x=0) and solve for y and similarly to find x-intercept we can set y-axis value to zero (y=0) and solve for x. let' start from basic formula of slope and prove.

m = (y - y

_{1})/(x - x

_{1})

m(x - x

_{1}) = (y - y

_{1})

y - y

_{1}= m(x - x

_{1})

in the case of y-intercept we can place 0 for x-axis and b for y-axis like (0, b)

so, y - b = m(x - 0)

=> y - b = mx

=> y = mx + b
