What is the slope of the line passing through (-3, 4) and (5, 2)?

Nnesha (nnesha):

\[\large\rm \frac{ y_2 -y_1 }{ x_2-x_1 }\]formula to find slope where x's and y's are \[\large\rm (x_1,y_1)(x_2,y_2) \rightarrow (-3,4)(5,2)\]

OpenStudy (anonymous):

I got -2/2

Nnesha (nnesha):

how did you get that what's x_1 ,x_2 and what are the y values ?

OpenStudy (anonymous):

You subtract y2 and y2 then do the same with the x's! Don't you?

Nnesha (nnesha):

yes correct

Nnesha (nnesha):

but remember one of the x is negative

OpenStudy (anonymous):

x is 2 thats what i got

Nnesha (nnesha):

no that's incorrect plugin x_1=-3 x_2 = 5

OpenStudy (anonymous):

Oh ok

OpenStudy (anonymous):

Now I have -2/8

Nnesha (nnesha):

good now just simplify

Nnesha (nnesha):
