Question

12x-3y -5=0
6x-1.5y-4=0
find the pair of graph​

Answer 1

Answer:

we can find the pair of graph by comparing coefficients

a1=12(coefficient of x) , b1= -3(coefficient of y) , c1= -5(constant)

a2=6 , b2=1.5 , c2=-4

to find the type of solution we should compare the ratios of the variables (a1,a2,c1...)

if a1 is not equal to b1 then it's unique

a2. b2

if a1 = b1 not equal to c1. it's no solution

a2. b2. c2

if a1 = b1 = c1. it's cosistent (infinite)

a2. b2. c2

the graph will be acording to the ratio

unique solution = intersecting

infinite solutions = coincident

no solution = parallel
