Given the linear equation 2x+3y–8=0, write another linear equation in two variables
Q6. Given the linear equation 2x + 3y – 8 = 0, write another linear equation in two variables such that the geometrical representation of the pair so formed is:
(i) intersecting lines (ii) parallel lines (iii) coincident lines
Solution
(i) intersecting lines
2x+3y-8=0
We know intersect lines
a1/a2≠b1/b2
we can write any equation according above formula
3x+5y-13=0
(ii) parallel lines
2x+3y-8=0
We know parallel lines
a1/a2=b1/b2≠c1/c2
we can write any equation according above formula
4x+6y-19=0
(iii) coincident lines
2x+3y-8=0
We know coincident lines
a1/a2=b1/b2=c1/c2
we can write any equation according above formula
6x+9y-24=0
