Part A. Circle Step A
====================================================================
Part B.
We must remember the following equation
Slope = \frac{y2-y1}{x2-x1}
Substitute numbers for x's and y's
Slope = \frac{165-90}{11-6}

Solve!
<span>Slope = \frac{165-90}{11-6}
</span>Slope = \frac{75}{5}
Slope = 15
====================================================================
Part C. She mixed up her X's and Y's.
Y's go on top and X's on the bottom

The formula for finding slope is y₁ - y₂ / x₁ - x₂, where y₁, y₂, x₁, and x₂ are coordinates of two given points, (x, y).

Hannah's error is that she placed the x-values in the numerator of the formula; the y-values go in the numerator, as shown above.

The correct substitution would be as follows.

165 - 90 / 11 - 6

To simplify this, subtract the numbers in the numerator and the denominator, and then divide.

165 - 90 / 11 - 6
75 / 5
15

Answer:
slope = 15

Which of the following rotational symmetry is applied to the regular not​
olya-2409 [2.1K]

9514 1404 393

Answer:

  • yes
  • yes

Step-by-step explanation:

A regular nonagon has vertices that are 360°/9 = 40° apart. Any rotation by a multiple of 40° will make the figure indistinguishable from the original.

Rotational symmetry of 40° applies.

Rotational symmetry of 200° applies.
