Coordinates (x, y)
Parallel lines have the same slope but different y-intercepts
An undefined line is a vertical line
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (3, 2)

Point (3, 1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{1-2}{3-3}$
[Fraction] Subtract: $\displaystyle m=\frac{-1}{0}$
Simplify: m = undefined

During a heavy rainstorm, a city in Florida received 12 1/2 inches of rain in 25 1/2 hours. What is the approximate rainfallrage

alexdok [17]

We need to divide the number of inches by the number of hours.
Let's first convert the two numbers into fractions.

12 1/2 = 25/2

25 1/2 = 51/2

(25/2) / (51/2) = 25/2 * 2/51 = 50/102 = 25/51 = 0.49

The average rainfall was approximately 0.5 inches per hour.

How do I find the slope of this altitude? I am referring to question 19.

Crazy boy [7]

The altitude's slope must be perpendicular to that of the line.

The slope of segment BC is 2/5. The slope of the altitude must be perpendicular to 2/5. Since the negative reciprocal of 2/5 is -5/2, then the slope of the altitude is -5/2.
