What is the slope of (-3,2) and (6,1)

evablogger [386]

Answer: -1/9

Step-by-step explanation:

Find the Slope (−3, 2) and (6, 1)

Slope is equal to the change in y over the change in x, or rise over run.

$m=\frac{change in y}{change in x}$

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called rise).

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

Substitute in the values of x and y into the equation to find the slope.

$m = \frac{1-(2)}{6-(-3)}$

Simplify the numerator. Tap for more steps...

$m=\frac{-1}{6-(-3)}$

Simplify the denominator.

$m=-\frac{1}{9}$

Answer:

The answer is "152 ft"

Step-by-step explanation:

Please find the attached file.

The area of the square $(8 \times 5=40)$ can be found on the foot.

The area of the triangular front will then be calculated $(6\times 4=\frac{24}{2} = 12).$

Since each has two sides, $24+80=104$ .

Therefore the multiplying the area of the bottom square $(6\times 8=48)$ by the number of cells to get 152.
