Question

If two points on a line are given by (-7, -1) and (-7, 12), we would say the line equation is?

Answer 1

`\large{ \tt{❃ \: SOLUTION}} :`

• Remember : To find the equation of straight line passing through given points ( x₁ , y₁ ) and ( x₂ , y₂ ) , Use
  `\tt{y - y_(1) = (y_(2) - y_(1))/(x_(2) - x_(1))(x - x_(1)})`

• Let the given points ( -7 , -1 ) be ( x₁ , y₁ ) & ( -7 , 12 ) be ( x₂ , y₂ ).

`\underline{ \large{\tt{❁ \: USING \: TWO - POINT \: FORM \: OF \: EQUATION \: OF \: LINE : }}}`

`\boxed{ \large{ \tt{❈ \: y - y_(1) = (y_(2) - y _(1))/(x_(2) - x_(1)) (x - x_(1))}}}`

`\large{ \tt{↦y - ( - 1) = (12 - ( - 1))/( - 7 - ( - 7)) \{x - ( - 7) \}}}`

`\large{ \tt{↦y + 1 = (12 + 1)/( - 7 + 7)(x + 7)} }`

`\large \tt \:↦ \: y + 1 = (12)/(0) (x + 7)`

`\large{ \tt{↦ \: y + 1 = 12(x + 7)}}`

`\large{ \tt{↦y + 1 = 12x + 96}}`

`\large{ \tt{↦ \: 12x + 96 = y + 1}}`

`\large{ \tt{↦ \: 12x - y + 96 - 1 = 0}}`

`\large{ \boxed{ \tt↦12x - y + 95 = 0}}`

• Hence , 12x - y + 95 = 0 is the required equation of the line.
