Answer:

The slope of a line is:

[tex]m=-3[/tex]

Hence, option B is true.

Step-by-step explanation:

Given the points

  • (-2, 9)
  • (0, 3)

Finding the slope between (-2, 9) and (0, 3)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-2,\:9\right),\:\left(x_2,\:y_2\right)=\left(0,\:3\right)[/tex]

[tex]m=\frac{3-9}{0-\left(-2\right)}[/tex]

[tex]m=-3[/tex]

Therefore, the slope of a line is:

[tex]m=-3[/tex]

Hence, option B is true.
