x=0
y=-3
Step-by-step explanation:
(Im going to add and subtract)
Add:
14x-12y=36
14x+9y=-27
28x-3y=9
Subtract:
-14x+12y=-36
14x+9y=-27
21y=-63
y=-3 (substitute in first equation)
7x+18=18
7x=0
x=0
SO
y=-3 and x=0

Gradient is just another similar term for slope l, 
, and it can be calculated by 
where 
and 1
is the 
-coordinates of point 
We let 
be point 
and 
be point 
, we can then write the equation:
.
It also says that the points are with a gradient of so 
. We can then write the equation:
