hi.

hartnn (hartnn):

use the slope formula \(\Large m=\dfrac{y_2-y_1}{x_2-x_1}\)

hartnn (hartnn):

where x1.,y1 = 2,7 x2,y2= -1,3

OpenStudy (anonymous):

I know that much, I just don't get how it transforms into like one fraction?

OpenStudy (anonymous):

I've already gotten that far, I just don't know where to go from there.

hartnn (hartnn):

what is y2-y1 = 3-7 = ... ?

OpenStudy (anonymous):

3-7=-4 and -1-2=-3

hartnn (hartnn):

so, m= -4/-3 = 4/3 :)

OpenStudy (anonymous):

Oh! Makes sense now. Thank you!

hartnn (hartnn):

welcome ^_^
