Pls work out and give detail. Use the slope formula to determine the slope of each line.
kolbaska11 [484]

Answer:

m=0

Step-by-step explanation:

Given

See attachment

Required

Determine the slope of the line

From the attachment, we have the following points

(x_1,y_1) = (-4,1)

and

(x_2,y_2) = (3,1)

The slope m is then calculated using:

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

Substitute values for the x's and y's

m = \frac{1-1}{3 - (-4)}

m = \frac{1-1}{3 +4}

m = \frac{0}{7}

m=0

<em>Hence, the slope is 0</em>

What is the area to this problem?
Nady [450]

Answer:

56 units²

Step-by-step explanation:

Each triangle has an area that is ...

... A = 1/2bh = 1/2·7·4

There are 4 such triangles, so the total area is ...

... 4A = 4(1/2)·7·4 = 2·7·4 = 56 . . . . units²

_____

An area formula customarily used when the diagonals are pependicular to each other is that the area is half the product of their lengths.

... A = (1/2)d1·d2 = (1/2)·14·8 = 56
