Question

Determine graphically the co-ordinates of the vertices of a triangle, the equation
of whose sides are y=x , 3y =x , x+ y = 8

Answer 1

Answer:

Step-by-step explanation:

Consider :1.x=y

2.3y=x

3.x+y=8

As three equations solve 1,3 we get,

y+y=8;y=4;

x+x=8;x=4;

One coordinate is (4,4)

Now solve eq 2,3 we get

3y+y=8;y=2

(x/3)+x=8;x=6

2nd coordinate is (6,2)

3rd coordinate is (0,0) itself center of your coordinate axes.
