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 = 1 cm 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)`.
