To verify whether the lones are
intercepting.
x+y = 8
4x-2y =
12.
Two lines are intersecting if they are not
parallel.
The given line are not parallel as the ratio of
coefficiet x and y of 1st line is not that of the other line. Or their slope are
different.
Let us solve the equations and the solution in x
and y coordinates are the point of intersection of the 2
lines.
x+y = 8 an
4x-2y =
12.
Eq(1)*2 + eq(2) elimintes
y:
(x+y)*2 +(4x-2y) = 8*2+12 =
28
6x = 28. x = 28/6 =
14/3.
So from (1) x+y= 8. Or y = 8-x = 8-14/3 =
10/3.
So (x,y) = (14/3 , 10/3) is the point of intersection
of the lines.
