jabez177 (jabez177):

I used that formula m= something, I forgot.

OpenStudy (anonymous):

OpenStudy (anonymous):

we will use 2 point form :)

OpenStudy (anonymous):

It says if you have a line passing through \(\large\ (x_1,~y_1)\) and \(\large\ (x_2,~y_2)\) then the equation of line is given as-> \(\huge{\frac{y-y_1}{y_2-y_1}=\frac{x-x_1}{x_2-x_1}}\)

OpenStudy (anonymous):

so do we know any 2 points that lie on the line ?:)

jabez177 (jabez177):

Yes. -3, 1 3, 4

OpenStudy (anonymous):

ok now try to put the values in the equation :)

jabez177 (jabez177):

OpenStudy (anonymous):

OpenStudy (anonymous):

no jabez neither A nor C is the ans we have 2 points|dw:1449008200753:dw| just put the values of \(x_1,~x_2,~y_1,~y_2\) in the equation be careful u put the right values
