Question

If a line goes through points (-2, 9) and (0, 3), what is its slope? 3 -3 6 -1/3

Answer 1

Answer:

The slope of a line is:

$m=-3$

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)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-2,\:9\right),\:\left(x_2,\:y_2\right)=\left(0,\:3\right)$

$m=\frac{3-9}{0-\left(-2\right)}$

$m=-3$

Therefore, the slope of a line is:

$m=-3$

Hence, option B is true.
