Answer:
Step-by-step explanation:
Slope m = rise / run = ( - ) / ( - )
<em>1).</em> (-4,3)
(4, - 1)
m = (-1 - 3) / (4 + 4) = <em>- 1/2</em>
<em>2).</em> (-1, 1)
(2, - 5)
m = (- 5 - 1) / (2 + 1) = <em>- 2</em>
<em>3).</em> (6, 4)
(5, 4)
m = (4 - 4) / (5 - 6) = <em>0</em> (graph is horizontal line)
<em>4).</em> (1, 4)
(4, 1)
m = (1 - 4) / (4 - 1) = <em>- 1</em>
<em>5).</em> - 3/4
<em>6).</em> 4/3
<u><em>Now is your turn. You can do it!!!</em></u>
<em>7).</em> (1, 1)
(2, 2)
m = ____
<em>8).</em> ( __ , __ )
( __ , __ )
m = _____
<em>9).</em> (0, 2)
(0, 4)
m = (4 - 2) / <u><em>(0 - 0)</em></u> = undefine slope or <em>no slope</em> (graph is vertical line)
<em>10).</em>
It's really hard to see and i know what you're working on! i'll be glad to help!
Answer:
400% area and 200% perimeter
Step-by-step explanation:
Given is a picture of a rectangle. (i.e. opposite sides are equal and all angles equal to 90 degrees)
We know for any rectangle with length l and width, w
Area of rectangle = lw and
Perimeter of rectangle = 2(l+w)
Suppose the side lengths are doubled
Now length = 2l and width = 2w
New ARea =
i.e. 400% times is the new area.
New perimeter =
New perimeter is 200% times the old perimeter.

A triangle has 180 degrees
180-25=155
15+16=31
155/31=5
15*5=75
16*5=80
The two angles are 75 degrees and 80 degrees.
