How do you find the x intercept in y=mx+b equation
Answered by Damon
The x axis intercept is the value of x when y = 0

0 = m x + b
m x = -b
x = -b/m

I dont get it
How did you find this out
Answered by Damon
I just used the equation you gave me (which is standard anyway)
y = m x + b
now I want to find out where that line hits the x axis
the x axis is where y = 0 (draw an x y graph)
so I set y to zero in your equation
0 = m x + b
then I subtracted b from both sides
then I divided both sides by m
