Farewell

Hi everybody,
It's been a great year!
I hope you have enjoyed the adventure of using real English in Maths and that you have a good time this summer. I'll see you next year.

P.S Don't forget to practise if you can !

Linear function

Properties of a Straight Line Graph

If y = m x is the equation of a function of proporcionality, what does m mean ?

Try to understand it with this link

This is a linear graph, but it's not a function of proporcionality

Q5.On sports day the first three in the 1 000 m race ran as shown in the graph below.

a) Wich runner, A, B or C, won the race?

b) How long did the winner take?

100. Which runner kept up a steady speed?

d)What was that speed

1. in m/min?

2. In km /h ?

e) Which runner achieved the fastest speed and what was that speed?

Q6. Two cars start a journey a midday(1200) one travels from A to B, and the other from B to A. The distance between A and B is 80 km. The speed of the first car is 48 km/h and the other car B travels at 60 km /h

The graph below shows these journeys

The page I showed last Friday in the class room is Figures Speak Mathematics.Click here if you want to revise what we saw. I think the title is true,any figure speaks mathematics you only have to look at it carefully.
