Find the area of the figure

Gwar [14]

Answer:

Step-by-step explanation:

This is simplest if we subtract the area of the missing rectangle from the area of a complete rectangle.

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m = \frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (9, 5)

Point (21, 1)

Step 2: Solve for slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{1-5}{21-9}$
[Fraction] Subtract: $\displaystyle m = \frac{-4}{12}$
[Fraction] Simplify: $\displaystyle m = \frac{-1}{3}$

A line passes through the two given points. Is it vertical, horizontal, or neither?

vova2212 [387]

To answer this question, let us find the slope using the coordinates:

(2, 1) and (3, 4)

1 - 4 / 2 - 3
-3 / -1
3

The slope is 3, so the answer is neither, since a horizontal line has a slope of 0 and the slope of a vertical line is undefined.
