Given the line below.
Roman55 [17]

Answer:

The equation of the line in point slope form is equal to

y+2=(x+2)

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

(-2,-2) and (2,2)

substitute the values

m=\frac{2+2}{2+2}=1

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=1\\(x1,y1)=(-2,-2)

substitute the values in the formula

y-(-2)=(1)(x-(-2))\\y+2=(x+2)

prisoha [69]

Answer:

<em>l</em> = 1 5/16

w = 1/16

A = 21/16 x 1/16 = 21/256

Step-by-step explanation:

Perimeter = 11/4

<em>l</em> = length

w = <em>l</em> - 5/4

2<em>l</em> + 2(<em>l</em> - 5/4) = 11/4

2<em>l</em> + 2<em>l</em> - -5/2 = 1/4

multiply each side by 4

8<em>l</em> + 8<em>l </em>- 10 = 11<em> </em>

16<em>l</em> = 21

<em>l</em> = 21/16 or 1 5/16

width = 21/16 - 20/16 = 1/16
