Find the slope and the y-intercept of the line 7x-2y=-8

slope = 7/2

y-int = 4

Step-by-step explanation:

parent formula is y=mx+b ; where m is slope and b is y-int.

begin by rewriting formula to isolate y ; 7x+8=2y ; divide bothe sides by 2 ; so

7/2 x+4=y. slope/m=7/2 and y-int/b=4

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
