Question

write any four linear equations and also write a,b,c values​

Answer 1

Question:-

Express the following linear equations in the form ax+by+c=0 and indicate the values of a,b and c in each case:

(i) 2x+3y=9.3

5

(ii) x−

5

y

−10=0

(iii) −2x+3y=6

(iv) x=3y

(v) 2x=−5y

(vi) 3x+2=0

(vii) y−2=0

(viii) 5=2x

Answer:

(i) 2x+3y=9.3

5

,c=−10

(iii) −2x+3y=6

⇒−2x+3y−6=0

Comparing the equation with ax+by+c=0

a=−2,b=3,c=−6

(iv) x=3y

⇒x−3y=0

Comparing the equation with ax+by+c=0

a=1,b=−3,c=0

(v) 2x=−5y

⇒2x+5y=0

Comparing the equation with ax+by+c=0

a=2,b=5,c=0

(vi) 3x+2=0

⇒3x+0y+2=0

Comparing the equation with ax+by+c=0

a=3,b=0,c=2

(vii) y−2=0

⇒0x+y−2=0

Comparing the equation with ax+by+c=0

a=0,b=1,c=−2

(viii) 5=2x

⇒−2x+0y+5

Comparing the equation with ax+by+c=0

a=−2,b=0,c=5
