hint: what is the slope of the graph?

Vocaloid
  • Vocaloid
nope
Vocaloid
  • Vocaloid
use the point slope formula
Vocaloid
  • Vocaloid
pick two points on the graph (0,0) and (2,9) = (x1,y1) and (x2,y2) then find m = slope = (y2-y1)/(x2-x1) = ?

y(y−1)/(x−1)
Vocaloid
  • Vocaloid
nope, read carefully.
anonymous
  • anonymous
y(y−1)/ x(x−1)
Vocaloid
  • Vocaloid
x1 = 0 y1 = 0 x2 = 2 y2 = 9 slope = (y2-y1)/(x2-x1) = ?

what is the slope ?
anonymous

90 / 20
Vocaloid
  • Vocaloid
almost.
Vocaloid
  • Vocaloid
y2 = 9 y1 = 0 y2-y1 = ?
anonymous
  • anonymous
9 / 2
Vocaloid
  • Vocaloid
good, now convert to decimal

good now p = (slope)(s)

old length = 8 new length = 5.5*old length = ?
anonymous
  • anonymous
44
Vocaloid
  • Vocaloid
good old width = 6 find the new width
anonymous
  • anonymous
264
Vocaloid
  • Vocaloid
no
Vocaloid
  • Vocaloid
remember, a scale factor of 5.5 means we multiply each dimension by 5.5
anonymous
  • anonymous
how do i find the nwe width
Vocaloid
  • Vocaloid
multiply the old width by the scale factor.....
Vocaloid
  • Vocaloid
follow the same pattern we used to find the length
anonymous
  • anonymous
242
Vocaloid
  • Vocaloid
no.
Vocaloid
  • Vocaloid
new width = scale factor*old width
anonymous
  • anonymous
33 @Vocaloid
Vocaloid
  • Vocaloid
good so we have length = 44 and width = 33 now find the perimeter and area.
anonymous
  • anonymous
how ?
Vocaloid
  • Vocaloid
please memorize these two equations. perimeter = 2(length+width) area = length*width
anonymous
  • anonymous
ok
Vocaloid
  • Vocaloid
now find the perimeter and area....
anonymous
  • anonymous
27?
Vocaloid
  • Vocaloid
no...
Vocaloid
  • Vocaloid
perimeter = 2(length+width) = ?
anonymous
  • anonymous
2 ( 8 + 5.5 )
Vocaloid
  • Vocaloid
no...
Vocaloid
  • Vocaloid
remember we just calculated length and width...
Vocaloid
  • Vocaloid
length = ? width = ? please look back at what we wrote earlier.
anonymous
  • anonymous
8 and 5.5
Vocaloid
  • Vocaloid
nope.
Vocaloid
  • Vocaloid
go back.
Vocaloid

Vocaloid
  • Vocaloid
nope.
Vocaloid
  • Vocaloid
read carefully.
anonymous
  • anonymous
im so confused
Vocaloid
  • Vocaloid
I already told you what the length and width were. what are they?
Vocaloid
  • Vocaloid
start from the beginning and read carefully.
anonymous
  • anonymous
8 and 5.5
Vocaloid
  • Vocaloid
nope.
Vocaloid
  • Vocaloid
pay attention. length = ?
anonymous

good. now find the perimeter and area.
anonymous
  • anonymous
what do i calculate to find the perimeter?
Vocaloid
  • Vocaloid
use the equations I just gave you.
anonymous
  • anonymous
154
Vocaloid
  • Vocaloid
good now find area.
anonymous
  • anonymous
how?
Vocaloid
  • Vocaloid
use. the. equation.

supplementary means they add up to 180. 7x + 33 = 180. solve for x.
anonymous
  • anonymous
x=21
anonymous

@Vocaloid

  • Vocaloid
typo
Vocaloid
