Call 1 = 5 min = $1.45
C2 = 14 min = $3.25

Linear y=mx+b
y =$, x = min

$1.45 = 5m + b
$3.25 = 14m + b

Subtract the two
-1.8 = -9 m
m= 0.2

y = 0.2x + b

Substitute into one linear eq to get b

$1.45 = 5m +b
1.45 = 5(0.2) + b
1.45-1= b
b = 0.45

NOW

y = 0.2x + 0.45



I gave up at this point and made a coffee

And they just accepted that?

My mom would be all "Who are you talking to, why are you doing that?"

Hm. Lucky

If I'm typing anything on the computer my mom wants to know who I'm talking to and what website I'm on. But that's just being her, at least I have my own laptop now and no key logger to tell her where I've been and what I say

Yeah, overprotective more like..

I haven't told her about any of the friends I've made on here, would like to but I don't trust that her reaction would be even tolerant of it.

Understandable.
I only tell my parents about a few though.
