do you know the slope formula?

sorta.. i forgot

what would the equation look like after you substitute the x's and y's?

2-5 / 2-1

(2-5)/(1-2)
when you decide which coordinate pair will be "1" and "2" you gotta keep it like that

so what's our slope?

idk ? im confused now

what's 2 - 5?

-3

and what's 1 - 2?

-1

right, so what's -3/-1?

exactly, so our slope is 3

do you understand how we got that?

sorta can u just explain it in simplier terms

|dw:1351215308811:dw|

|dw:1351215523686:dw|

okay so part a : is slope is 3 and part b is ?

do you know what point-slope form is?

YES. im just confused on now part b

y = 3x and what for slope form

what? point-slope form is y - y1 = m(x - x1)

(2-5)/(1-2)

you haven't done part b yet

do you know how to change that into slope-intercept form?

no

y = 3x-1?

that's right :D

thanks . i have a few more questions i need help with i would like help with them
