1. Gcse maths question
t = a√s + b

I've got the values
s=2.8 when t=7.2
s=4.6 when t=8.7
s=12.4 when t=13.1

I've got the find the values of a and b by drawing a graph, but i've drawn one and i'm still none the wiser >.<
2. Re: Gcse maths question
b=point line crosses y axis
when you plot a graph of t against √s
3. Re: Gcse maths question
b = t intercept

4. Re: Gcse maths question
Did you plot t against s? you should use t against root s
5. Re: Gcse maths question
Ah! I've plotted the graph wrong, thanks all :P
