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

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

Solve!
Slope = [tex] \frac{165-90}{11-6} [/tex]
Slope = [tex] \frac{75}{5} [/tex]
Slope = 15

Part C. She mixed up her X's and Y's.
Y's go on top and X's on the bottom
