Relationship between study time (T) and exam mark (M) is estimated to be M^=20+5 * T
Interpret both coefficients
Can anyone explain what I’m meant to do

- Think about what happens when T = 0
- Think about what happens as T changes e.g. from T = 1 to T = 2

Maybe think about it like a graph, can you equate this to y=mx+c? What would be the relationship in the graph? If you can't visualise it pick some points e.g. T=1,2,3,4,5 and plot these points to help you

So it would be
M = 20 + 5 * 1
M= 20+ 5 * 2
And then explain what’s happening?

How does M change when T increases by 1? And how does that relate to the '5' coefficient?
