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

Scrat [10]

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.

Can u explain how to solve this?

Answer: B.pi/2

ABCD is a square

=> Δ ABD is a isosceles right triangle at A

using pythago theorem, we have:

AB² + AD² = BD²

=> 2AD² = 4

⇔ AD² = 2

⇒ AD = √2

through O, draw EF parallel to AD and BC

=> EF is diameter

because EF//AD => EF = AD = √2 (because circle O is inscribed the square ABCD)

=> the area of the circle is $S=\frac{(\sqrt{2})^{2} }{4}.\pi =\frac{\pi }{2}$
