Sounds like Tracy is averaging three photos a day so she would take 21 in seven days

P=pictures
d=days of vacation
12p=4d
divide both sides by 4 to get
3p=d
3pictures every day
21p=_d, 21/3=7
7 days!

Find the slope of the line that passes through (2, 1) and (6,2).

Sergio [31]

Answer:

$\boxed{m = \frac{1}{4}}$

Step-by-step explanation:

Use the form below

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

Where

$m$ is a slope
$(x_1,~y_1)$ and $(x_2,~y_2)$ are the point of the line

So, the slope is

$(2,~ 1) \to x_1 = 2~and~y_1 = 1$

$(6,~ 2) \to x_2 = 6~and~y_2 = 2$

$m = \frac{2-1}{6-2}$

$m = \frac{1}{4}$

Happy to help:)
