Question

verify the condition of consistency and inconsistency for a pair of linear equation in two variable by geographical method in graph​

Answer 1

Answer:

if a1/a2 = b1/b2 = c1/c2, then the lines are coincident on the graph

in this case, there are infinite solutions and so it is consistent

if a1/a2=b1=b2$\neq$ c1/c2, then the lines are parallel

here, there is no solution as the lines do not meet and it is inconsistent

if a1/a2 $\neq$ b1/b2, the lines meet at a point and are intersecting

hence, there is only 1 soln. and these are consistent equations

*im not sure what to verify with and so i hope you understand from this

thank you, hope this helped :)
