Which pairs of points would result in a line with a rate of change of 2:1? select all that apply
Reil [10]

Answer:

A,C,D

Step-by-step explanation:

Complete Question:

<em>"Which pairs of points would result in a line with a rate of change of 2:1? select all that apply"</em>

<em>A.(−4,−11) and (−2−7) </em>

<em>B.(5,6) and (−5, 12) </em>

<em>C.(0,−3)and (−4,−11) </em>

<em>D. (0,−3) and (5, 7)</em>

<em />

Rate of change is the slope. 2:1 would mean a slope of simply, 2.

We need to find slope of each of the choices from A - D and see which one has 2. The formula would be:

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

Where m is the slope and

x_1 is first x point

x_2 is second x point

y_1 is first y point

y_2 is second y point

Let's calculate slope of each of the choices.

A.

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{-7+11}{-2+4}\\m=2

THis one is okay.

B.

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{12-6}{-5-5}\\m=-\frac{3}{5}

THis one is not 2:1.

C.

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{-11+3}{-4-0}\\m=2

THis one is okay.

D.

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{7+3}{5-0}\\m=2

This one is okay.

Hence, A, C, and D all have rate of change of 2:1

Jenna is running a trail that is 8 4/7 miles long. If she has finished running 5/9 of the distance, about how far has she run?
Varvara68 [4.7K]

Answer:

Jenna has run the distance of \frac{100}{21} miles .

Step-by-step explanation:

The Distance for the trail = 8 \frac{4}{7} =  \frac{56+4}{7}

Or , Distance =  \frac{60}{7} miles

The distance cover by Jenna =  \frac{5}{9} miles of the distance

I.e The distance cover by Jenna =  \frac{5}{9} ×  \frac{60}{7}

Or, The distance cover by Jenna =  \frac{100}{21} miles

Hence Jenna has run the distance of \frac{100}{21} miles . Answer
