Question

Determine graphically the vertices of the triangle, the equations of whose sides are given below: (i) (ii)

Philoid · Accepted Answer

(i)

2y – x = 8 passes through (-8, 0) and (0, 4)

5y – x = 14 passes through (-14, 0) and (0, 14/5)

Y – 2x = 1 passes through (0, 1) and (-1/2, 0)

Vertices of the triangle are (-4, 2), (1, 3) and (2, 5)

(ii)

3x + 3y = 10 passes through (10/3, 0) and (0, 10/3)

Vertices of the triangle are (0, 0), (10/3, 0) and (5/3, 5/3)
