If the slope of the line (a x+(3-a) y+7=0 ) is 7 then the value of integral part of ' (a ) ' is

Options

  1. A3
  2. B7
  3. C0.5
  4. D3.5

Correct answer

A. 3

Step-by-step solution

Given line (a x+(3-a) y+7=0 ) Given slope (=7 ) ( aligned -a 3-a & =7 a 3-a & =7 a & =7 a-21 6 a & =21 a & = 7 2 a & =3.5 a & =3+0.5 [a] & =3 aligned ) Hence, option (a) is correct.
