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.
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.
Equation of a straight line using formula
y = mx + b
m = (y - y1)/(x - x1)
m(x - x1) = (y - y1)
y - y1 = m(x - x1)
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
