dude:

Rise: How many units it goes up Run: How many units it goes across Does that make sense?

Nicole:

So 2+1/3? or 2+3/3 ?

dude:

No no its just Slope = \(\frac{Rise}{Run}=\large\frac{1+1}{1}\)

Nicole:

oh so its B lol

dude:

Yep

dude:

Slope equation for two points \(\large \frac{y_2-y_1}{x_2-x_1}\) First point would be \((x_1,y_1)\) and second would be \((x_2,y_2)\)

Nicole:

wouldnt the first point be (y2−y1) and the second (x2−x1)

dude:

y, values haha A point is written as (x,y)

Nicole:

Oh trueee lol myb

Nicole:

(-7-1)/(5-3)

dude:

Not quite \(\large \frac{-7-3}{5-1}\)

Nicole:

Ohh -5/2

dude:

Right
