Answer:
- y = 3x + 4
- y =
x - 1 - y = 4
- undefined
Step-by-step explanation:
Slope-intercept form is written in the form: <em>y </em>=<em> mx </em>+<em> b</em>. Leave the y and x as they are. The m is the slope of the graph. The b is the y-intercept of the graph. For number three, the slope of a horizontal line is 0. For number four, the slope of a vertical line is undefined.
Hope it helps! (I'm not sure if you need the answers to the bottom questions).

Answer:
x^2 + 2x +1 = 2x + 2
Step-by-step explanation:
(x+1) = 2
multiplying both sides by x +1
(x +1) (x+1) = 2 (x+1)
x^2 + 2x +1 = 2x + 2
To find area you have to do length times width, and for squares, you just multiply the length or width by itself since a square's length and width are the same. Since you know that the side length of the square is 5√9, you multiply 5√9 by 5√9. First you multiply 5 by 5 which is 25, then you multiply √9 by √9 which is 9. Then you multiply 9*25 and you get that the area of the square is 225.
