Following the Slope-Intercept Form,, we can get the Y-intercept, by substituting given:
--->
, Y-intercept
It follows eqn, , Multiply the whole eqn by "7":
---> } Standard Form, (Answer)
Find X-intercept:
:
--->
, ==> (97/6,0) or (16.2,0)
Find Y-intercept:
--->
, ==> (0,-97/7) or (0,-13.9)
Thank you,

starting with the standard slope intercept form,,,y=mx+b
.
if m= (6/7) ,,,and (8, -7),,,,,,,,,substituting
.
(-7) = (6/7)(8) +b
.
-7 -48/7= b
.
-7 -6 6/7 =b
.
b= -13 6/7
.
reviewing the std eqn,,,y = 6/7 *x - 13 6/7,,,answer in slope intercept form
.
multiplying by 7
.
7y =6x - 97
.
or,,,,-6x +7y = -97,,,,mult by -1
.
6x -7y =97,,,,,answer in std form..
.
.
checking,,( 8,-7),,,,,6(8) -7(-7) = 97,,,,,ok
.
