Choice two point from the graph (look at the picture).

(0, 2) and (3, -2).

The formula of a slope:

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

Substitute:

$m=\dfrac{-2-2}{3-0}=\dfrac{-4}{3}=-\dfrac{4}{3}$

Answer: The slope of this line is $\boxed{m=-\dfrac{4}{3}}$

In a scale model of the Eiffel Tower, 10 centimeters represent 65 meters. If the real Eiffel Tower is approximately 325 meters t

kupik [55]

Answer:

The plastic model is 50 meters tall

Step-by-step explanation:

Here, we want to know how tall is the plastic model

In the plastic model 10 m represents 65 meters

then x meters plastic = 325 m real

10 * 325 = 65 * x

3250 = 65x

x = 3250/65

x = 50 meters

A farmer has two pieces of land in a parallelogram shape on the same base. He grows vegetables and flowers in two triangular pie

Hitman42 [59]

Step-by-step explanation:

In trapezoid ABCF, AB || CF.

Therefore, parallelograms ABEF & ABCD have same height and lie on the same base AB.

$\therefore Ar(\parallel^{gm} ABEF) = Ar(\parallel^{gm}ABCD)\\... (1)\\\\ \because\: Ar(\parallel^{gm} ABEF) \\=Ar(\triangle AFD) + Ar(\square \: ABED)....(2) \\\\\&\: Ar(\parallel^{gm}ABCD)\\= Ar(\triangle BCE) +Ar(\square ABED)....(3)$

From equations (1), (2) & (3), we find:

$Ar(\triangle AFD) + Ar(\square \: ABED) \\ = Ar(\triangle BCE) +Ar(\square ABED) \\ \\ \purple {\boxed {\therefore Ar(\triangle AFD) = Ar(\triangle BCE)}} \\$

Thus, the two triangular pieces of land are equal in area.

Hence proved.

(-1,5) (0,2) in slope intercept form

xeze [42]

Answer:

Step-by-step explanation:

(-1,5) (0,2)

y2= 2, y1 = 5, x2 = 0, x1 = -1

Slope m = [y2 - y1]/[x2 - x1]

m = {2 - 5}/{0+1}

m = -3/1

m = -3

And

y - y1 = m(x - x1)

y - 5 = -3(x + 1)

y - 5 = -3x - 3

y = -3x - 3 + 5

y = -3x + 2
