Help!

Answer 1

@ganeshie8

Answer 2

Look at the line,
it is going thru (0, 0) right ?

Answer 3

can u figure out the slope of line ?

Answer 4

Wait, What?

Answer 5

I bet u heard of "slope" before, eh ?

Answer 6

Yeah xD

Answer 7

It goes up, and across one

Answer 8

@ganeshie8?

Answer 9

yes, and it goes right by 1 unit
so slope = 1/1 = 1

Answer 10

so you have slope = 1, and y-intercept = 0
can u write the equation of line ?

Answer 11

equation of line in slope-intercept form :
\(y = mx + b \)

m = slope
b = y-intercept

Answer 12

y=1x?

Answer 13

^ yes !

Answer 14

in function notation it wud be :

\(f(x) = x \)

Answer 15

Ohh ok! I get it!

Answer 16

good :)

Answer 17

Thanks!
