[hamza96]

and how to find the co-ordinates of a line?

 

[Iridescent]

the coordinates of a line are found by the equation of the line. a value can be substituted for either of the coordinates(x or y) and the corresponding value can be found for the other variable by solving the equation.
e.g: if the equation of a line is y=2x if we take x as 1, y will be 2*1=2, if x=4, y=2*4=8.
coordinates can be found like this and the line can be plotted.

ohhh thanxxx............and one more thing.....tommorow i have my paper 2 exam..........and im very scred about dat.......any expectationvof questions for oct/nov 2011............and which topic shud i really noe for dat...??

 

[Bouchra]

for the first question, I'm sure there's an easier way but I'm in a hurry so I'll give you this way

find 2 times itself how many times = 32

like 2 x 2 x 2 = 8, thats 2 to the power 3, in the same manner find 2 to power n = 32.

I hope you got it.

May Allah help us answer the questions correctly.

Pray for me, I have an exam in a couple of hours.
