A line can be defined in general form by the equation Ax+By = C where A, B and C are constants. You may assume that both A and B are non-zero. Then the slope of the line is , its x intercept is , and its y intercept is . Of course your answers will depend on A, B, and C.

hartnn (hartnn):

isolate 'y' from Ax+By =C

hartnn (hartnn):

then compare your equation with y=mx+c slope = m

hartnn (hartnn):

To get x-intercept put y=0 in the equation to get y-intercept put x=0 in the equation

OpenStudy (anonymous):

so my slope would be -A/B?

hartnn (hartnn):

yes.

OpenStudy (anonymous):

then C/B would be my Y

hartnn (hartnn):

correct

OpenStudy (anonymous):

then to find x intercept i put 0 on the Y

hartnn (hartnn):

yes

OpenStudy (anonymous):

then it would be -B/A?

hartnn (hartnn):

no...

OpenStudy (anonymous):

hmm

hartnn (hartnn):

Ax+By =C y=0 Ax=C x= .. ?

OpenStudy (anonymous):

AC

hartnn (hartnn):

no...

OpenStudy (anonymous):

C/A

hartnn (hartnn):

yes

OpenStudy (anonymous):

awsome

hartnn (hartnn):

and easy :)
