How do you graph this??

[Josh]

y = 5x + 3

I know its a simple thing but I completely forgot how to do it..

would you just substitute values like:

if x = 0 then y = 3 (0,3)
if y = 0 then x = -3/5 ??
if x = 1 then y = 8 ?

is this how you go about doing it?

Would the graph look like this?

 

[sohcrates]

you're method is correct sir. it will give you a rough graph

 

[minendo]

slope = 5
y intercept = 3 (i think, it might be the x intercept)

 

[Koing]

<< slope = 5
y intercept = 3 (i think, it might be the x intercept) >>



correct

y=mx+c

m = gradient

c = y intercept

Would this look like the graph?

Something like that... Here is a more accurate graph i cooked up right quick.

Google is your friend

Lol.


Gr. 10 math.

Yes, as poeple have alreayd said, Y-int is 3, slope is 5, that's all you need to know.

Your 'graphs' are correct, but please, do get a graphing calculator. There are some good free ones available.
