my friend, this is why man created the $80 plastic graphing calculator that can solve math problems and write funny words with letters when you turn the thing upsidedown

80085...lol

ahahahahah!

and 1337 dont forget 1337.calculators dont do much good for these problems

can x= anything? somethings I choose for x dont make a striaght line

yep, if you y = x2 (squared) that produces a curve, as does x3 (cubed)



take the general formulae, y=mx + c
where m = gradient and c = the y intercept

if you change these values it has an effect on the graph too:



as you can see, if you change the number before the x, the m value this alters the gradient. but if you change the y intercept value, the c value at the end that changes where the graph crosses the y axis.

it helps to rember the general formulae, the y=mx+c, that way you can quickly identify the gradient and y intercept. another way to help you plot the graphs is by drawing tables, ill show you quickly a table for the graph of y=x2 (squared)



you would then plot these onto the graph, to give you the y=x2 graph above.


lol thats all for the min... gotta go do my own maths homework... hehe
