Question

8. Determine graphically whether the following pairs of equations are consistent or inconsistent:
(i) x - 5y = 6, 2x - 10y = 12
(ii) 2x - 3y = 6, X - Y = 0​

Answer 1

Answer:

(i) consistent

(ii) consistent

Step-by-step explanation:

(i) x - 5y - 6 = 0

  2x - 10y -12 = 0

a1 = 1                  a2 = 2

                          b2= -10

                          c2 = -12

b1 = -5

c1 = -6  

a1/a2=b1/b2=c1/c2             [1/2=1/2=1/2]
