Answer:
Step-by-step explanation:
When you factor each equation, you result in two of the factors canceling out, resulting in .
[Top Equation]
The middle number is 3 and the last number is -28.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 3
Multiply together to get -28
Can you think of the two numbers?
Try -4 and 7:
-4+7 = 3
-4*7 = -28
Fill in the blanks in
(x+_)(x+_)
with -4 and 7 to get...
(x-4)(x+7)
[Bottom Equation]
The middle number is -7 and the last number is 12.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -7
Multiply together to get 12
Can you think of the two numbers?
Try -3 and -4:
-3+-4 = -7
-3*-4 = 12
Fill in the blanks in
(x+_)(x+_)
with -3 and -4 to get...
(x-3)(x-4)

Answer:
Step-by-step explanation:
The only thing important in this question in the original equation is the slope, which is 3, the multiplyer for x. To find the opposite slope follow the steps below.
The first step is to make the original slope into a fraction.
Then flip the numerator and denominator.
Now multiply this value by -1.
There is the opposite slope of 3.
