Answer:

use 2 defined points.

Lets use: (-3,0) and (0,3)

The equation is written as y = mx+b, where m is the slope and  is the y-intercept

Slope - change in y / change in x:

Slope = (3 -0) /(0- -3) = 3/3  = 1

b is the y-intercept which is the y value when x is o, which is one of the points (0,3) so b = 3

The equation becomes y = x +3

The area of a square bedroom is 144 square feet. what is the length of one wall?
Rufina [12.5K]
The answer is:  "12 feet" .
________________________________
Note:  In a square, the length of EACH of the four sides of the square is the same.

Area = Length * width. 

For a square, length = width.

So for a square, Area = length * width = (length of a side)² = s² ,

Given:  A = s² = 144 ft² ;

Solve for the positive value of "s" .
________________________________
  →  s² = 144 ft² ;  Take the "square root" of each side ;

  → √(s²) = √(144 ft²) ;

  →   s = 12 ft.
_______________________________
The answer is:  12 ft.

Find the hypotenuse of each Isosceles right triangle when the legs are of the given measure.
ludmilkaskok [199]

Answer:

12

Step-by-step explanation:

We can use the pythagorean theorem giving us:

a^2+b^2=c^2

(6sqr2)^2 + (6sqr2)^2 = c^2

72+72=c^2

144=c^2

12=c
