It takes 45 minutes because if you do 6 divided by 2 you get 3 and then you do 3 x 15 you get 45. So 45 is your answer

Find the slope of the line through (2,-2) and 5,-1)
Kitty [74]

Answer:

m=\frac{1}{3}

Step-by-step explanation:

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(2,\:-2\right),\:\\\left(x_2,\:y_2\right)=\left(5,\:-1\right)\\\\m=\frac{-1-\left(-2\right)}{5-2}\\\\m = \frac{-1+2}{3}\\ \\Simplify\\m = \frac{1}{3}

Debi walks laps around the mall for exercise during the winter months. The table represents the number of steps recorded on her
MariettaO [177]

Answer:

<em>The correct option will be:   b. One lap around the mall is equal to about 2,425 steps.</em>

Step-by-step explanation:

Here, we will just find <u>the slope of the line representing Debi’s data</u>. For that, we will take any two data from the table in form of point like (x,y)

Lets take two points as  (0, 1875) and  (2, 6725)

<u>Formula for finding the slope</u> is:  m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}} , where (x_{1}, y_{1}) and (x_{2}, y_{2}) are two given points.

Here,  x_{1}= 0 , y_{1}= 1875 , x_{2}=2 , y_{2}=6725

So, plugging these values into the above formula, we will get......

m= \frac{6725-1875}{2-0}=\frac{4850}{2}=2425

That means, one lap around the mall is equal to about 2,425 steps.
