Find the slope of the line shown below

WITCHER [35]

Answer:

$\frac{3}{2}$

Step-by-step explanation:

From the attached photo, we can deduce:

(2,2) as (x1,y1)

(-2,-4) as (x2,y2)

Slope Formula =

$\frac{y1 - y2}{x1 - x2}$

Now we can substitute these values into the formula to find the slope.

Slope of line =

$\frac{2 - ( - 4)}{2 - ( - 2)} \\ = \frac{2 + 4}{2 + 2} \\ = \frac{6}{4} \\ = \frac{3}{2} (reduced \: to \: simplest \: form)$

What is the scale of the drawing?

Murrr4er [49]

The ratio of the areas is

$16\textrm{ cm} \times 8 \textrm{ cm} : 72 \textrm{ sq m}$

$16 \times 8 \textrm{ cm}^2 : 9 \times 8 \textrm{ m}^2$

$16 \textrm{ cm}^2 : 9\textrm{ m}^2$

The scale is the ratio of the lengths, which is the square root:

$4 \textrm{ cm} : 3 \textrm{ m}$

Answer:

Step-by-step explanation:

Let tacos be x and burritos be y

So, Avery purchased 4x+2y = 21

Sasha purchased 4x+3y = 26.5

Solving the 2 eqns:

4x+2y=21

-4x-3y=-26.5

-y=-5.5

The cost of one burrito is $5.5
