Answer:

So basically you have to create a set of coordinates like (3,2) to create a linear function. Make sure to make a linear equation and represent it through a graph or table. Then take its coordinates.

An example is the table I attached. It is a linear function.

y = 4x is the linear equation.

(2,8) is the coordinate.

Hope I helped in time!

Here are two rectangles.

Sophie [7]

Answer:

$AB=9.5\ cm$

Step-by-step explanation:

step 1

Find the length side PQ

we know that

The area of rectangle PQRS is given by

$A=(PQ)(QR)$

$A=66\ cm^2$

$66=(PQ)(QR)$

substitute the value of QR

$66=(PQ)(12)$

solve for PQ

$PQ=66/12\\PQ=5.5\ cm$

step 2

Find the length side AB

we know that

The perimeter of rectangle ABCD is given by

$P=2(AB+BC)$

we have

$P=30\ cm\\BC=PQ=5.5\ cm$

substitute

$30=2(AB+5.5)$

solve for AB

$15=AB+5.5\\AB=15-5.5\\AB=9.5\ cm$

Write y+1=5/2(x-2)+2 in standard form step by step please

Elden [556K]

Answer: 5x - 2y = 8

y+1=5/2(x-2)+2

multiply the each side by 2 to get rid of the fraction

2 (y+1) = (5/2 (x-2) +2 )2

2y+2=5(x-2)+4

now distribute the 5

2y+2=5x-10+4

subtract the two from each side

2y=5x-10+4-2

add like terms

2y=5x-8

subtract 5x from each side

2y-5x=-8

multiple the whole equation by -1 to make the 5x a positive

-2y+5x=8

hope this helps!
