Question

Determine graphically the vertices of the triangle, the equations of whose sides are given below :

y = x, y = 0 and 3x + 3y = 10

Answer 1

Draw the 3 lines as given by equations

By taking x=1 = 1 cm on x−axis

And y =1=1cm on y−axis

y = 0

y = x

`y/"10/3" + x/"10/3" = 1`

From graph point of intersection are (0,0) (10/3,0) (5/3,5/3)
