Since 1 and 2 are linear and 3 and 2 are supplementary that means 1 and 3 are congruent; because 1=2 and 2=3 that would mean 1=3

The length and width of the park are measured in linear units: inches, miles, meters, etc. The area is measured in square units.

Strike441 [17]

Answer:

In the area formula, there are two dimensions that are multiplied, base and height. So, the units are also multiplied. Inches times inches is inches squared. Also, area is a measurement that counts how many squares fit inside of a shape, so it makes sense that the units are described as squared.

Consider the line that passes through each pair of given points, and decide what type of slope the line has.

tatiyna

Answer:

The types of slope for each pair are:

(2, 4) and (5, 1) => Negative

(3,5) and (-1,2) => Positive

(-7, 8) and (-7,0) => Undefined

(6.-3) and (4, -3) => Zero

Step-by-step explanation:

We will find the slope of each line to check the type of slope.

Slope is given by the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point

Now,

<u>(2, 4) and (5, 1)</u>

$m = \frac{1-4}{5-2} = \frac{-3}{3} =-1$

The slope is negative.

<u>(3,5) and (-1,2)</u>

$m = \frac{2-5}{-1-3} = \frac{-3}{-4} = \frac{3}{4}$

The slope is positive

(-7, 8) and (-7,0)

$m = \frac{0-8}{-7+7} = \frac{-8}{0}$

division by zero makes the slope undefined.

(6.-3) and (4, -3)

$m=\frac{-3+3}{4-6} = \frac{0}{-2} = 0$

The slope is zero

Hence,

The types of slope for each pair are:

(2, 4) and (5, 1) => Negative

(3,5) and (-1,2) => Positive

(-7, 8) and (-7,0) => Undefined

(6.-3) and (4, -3) => Zero
