Find the slope of the line through the pair of points. A(2, –3), P(2, 9)

Flauer [41]

The slope: $m=\dfrac{y_2-y_1}{x_2-x_1}$

$A(2;-3)\to x_1=2;\ y_1=-3\\P(2;\ 9)\to x_2=2;\ y_2=9\\\\subtitute:\\\\m=\dfrac{9-(-3)}{2-2}=\dfrac{12}{0}!!!$

The denominator can not be zero!

Conclusion: The slope is undenfined.

What is the equation in point-slope form of the line that passes through (-9, 12) with a slope of 5/6?

Hitman42 [59]

Answer:

$\large\boxed{y-12=\dfrac{5}{6}(x+9)}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point on a line

We have

$m=\dfrac{5}{6},\ (-9,\ 12)\to x_1=-9,\ y_1=12$

Substitute:

$y-12=\dfrac{5}{6}(x-(-9))\\\\y-12=\dfrac{5}{6}(x+9)$

Answer:

i) ∠AOB = 87°

ii) ∠BOC = 72°

iii) ∠COD = 123°

iv) ∠AOD = 78°

Step-by-step explanation:

The first three angle measures can be read from the diagram. Find the rays that define the angle, and read the measure of the arc between them.

The last angle, AOD, is found using the fact that the sum of all of the angles around a point is 360°.

87° +72° +123° +∠AOD = 360°

∠AOD = 360° -282° . . . . . . . . . . subtract 282° from both sides

∠AOD = 78°
