Hi everyone,
since two days I'm following the lesson 18.01SC and I don't really understand this:
In Session 2, Clip 2 he explaines that to get the xintercept of the triangle you have to use this formula:
y  y0 = m (x  x0)
with:
y = 0, because it is an intercept with the xaxes.
y0 = 1/x0
m = 1/x0^2
x = x
x0 = x0
But I don't get why it is y  y0 and not just y0 and why it is m (x  x0)...
Could someone please help me with this? If it is a bit of a stupid question, I'm sorry.
