The -1 affects the coefficient of the entire term.
Without the -1,
the term has a positive coefficient.
(3a)² = 9a²
However, with the -1,
the term has a negative coefficient.
-(3a)² = -9a²
Hey there! :D
Plug in the points to see if they work.
y=7x
(2,14) -> (x,y)
14=7*2
14=14
That works.
(0,0)
0=7*0
0=0
That works
(1,7)
7=7*1
7=7
That works.
The points that work are (2,14), (0,0), and (1,7)
I hope this helps!

Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.
The answer is 101
100 squared is 10,000
Then form an equation
100u-100=10,000
+100 +100
100u=10,100
divide by 100 on both sides
and you get 101 as the answer
A percentage is a comparison to 100, so
250% = 250/100 = 25/10 = 5/2
5/2 = 2 1/2 or 2.5
