Answer:

  • A) y - 3 = - 2(x - 2)

========================

Point-slope form is:

  • y - y₁ = m(x - x₁), where (x₁, y₁) is the coordinates of the point, m is the slope

Substitute the values to get:

  • x₁ = 2, y₁ = 3, m = - 2
  • y - 3 = - 2(x - 2)

The matching choice is A

Answer:

[tex]\textsf{A.} \quad y-3=-2(x-2)[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Point-slope form of a linear equation}\\\\$y-y_1=m(x-x_1)$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $(x_1,y_1)$ is a point on the line.\\\end{minipage}}[/tex]

Given values:

  • m = -2
  • (x₁, y₁) = (2, 3)

To find the equation of the line in point-slope form, substitute the given slope and point into the point-slope formula:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-3=-2(x-2)[/tex]
