It’s probably some glitch or you moved up a level? Maybe try reloading again or somthinlike that
14x+2y=6 (1)
-7x-2y= -13 (2)
Multiply (2) by 2, we have:
-14x-4y= -26 (3)
Take (1)+(3), we can solve and get x= -1, y= 10~
The equation of the line passing through
and
is
. Here
is the slope of the line.
Substituting numerical values, the equation of the line is

The equation of the line is
