\blue\textsf{\textbf{\underline{\underline{Question:-}}}}

Write an equation in point-slope form for the line that has a slope of \bold{\dfrac{1}{5} } and contains the point (2, -9).

\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

\sf{Formula\:for\:Point-Slope:-}

\dashrightarrow\bigstar\star\boxed{\bold{y-y_1=m(x-x_1)}}\star\bigstar\dashleftarrow

Where

y₁ = the y-coordinate of the point that the line contains

m = slope

x₁ = the x-coordinate of the point that the line contains

Provided Information:-

y₁ = -9

m = \dfrac{1}{5}

x₁ = 2

Substitute the values:-

         \sf{y-(-9)=\dfrac{1}{5} (x-2)}

    On simplification,

          \sf{y+9=\dfrac{1}{5}(x-2)}

According to the answer and explanation, we conclude that

       [<u>The correct answer is Option B]</u>

elena-14-01-66 [18.8K]

Answer:

{x}^{2}  + 4x - 9 = 5x + 3 \\  {x }^{2}  - x - 12 \\  {x}^{2}  - 4x + 3x - 12 \\ x(x - 4) + 3(x - 4) \\ (x - 4)(x + 3) \\ x = 4 \: and - 3
