Question

find graphically the coordinates of the Vertices of a triangle formed by lines represented by equation y=0;y=4x;x-3y=-6

Answer 1

solving these three equations by taking two at a time we find three values of x and y. these three points will be vertices of the triangle.
solving we get
1.solving
y=0 and y= 4x
we get. (0,0)
2.slving
y=0 and x-3y=6
we get (6,0)
3. solving
y=4x and x-3y=6
we get (-6/11,-24/11)
so these are vertices of triangle.
