(a) Slope is rise over run, or change in y over change in x.

1 -> 3 ( $\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{4 - -8}{-1 - -5} = \frac{4 + 8}{-1 +5}= \frac{12}{4} =\frac{12}{4}$ )

2 -> 3 ( $\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{1 - 7}{0 - 2} = \frac{-6}{- 2} =\frac{6}{2}$ )

3 -> -1/3 ( $\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{-7 - -3}{6 - -6}= \frac{-7+3}{6+6}=\frac{-4}{12}=-\frac{1}{3}$ )

(b) If a line is parallel, the slopes will be the same. If they are perpendicular, the slopes will be are negative reciprocals of one another. If they are neither, then their slopes don't match up in any way.

1 & 2 -> Parallel

1 & 3 -> Perpendicular

2 & 3 -> Perpendicular

Note - Since 1 & 2 are parallel, then both 1 and 2 will be perpendicular to 3!

Have a nice day!

An official stands 2 meters from the edge of a discus circle and 3 meters from a point of tangency How far is the official from

Pachacha [2.7K]

Answer: 3.25 m

Step-by-step explanation:

as a tangency and a radius make a right angle, we can use Pythagoras.

c² = a² + b²

(r + 2)² = r² + 3²

r² + 4r + 4 = r² + 9

4r = 5

r = 1.25 m

so the official is standing 1.25 + 2 = 3.25 m from the center of the circle

This makes sense as a standard discus throwing circle is 2.5 m dia.
