The equation for working out the slope of a linear line is: 
, where x and y are the coordinate pairs.
So just pick two of the purple dots on the graph and fill in the equation.
I'll pick the dot that's (-4, 1) and (4, -7).
Now I just do 
, which is just 
when simplified.
I could explain it, but you have to ask me, other than that the answer is 5(x+7)(9x-4).
Answer:
Step-by-step explanation:
28 = 2 * 2 * 7
35 = 5 * 7
The common factor is 7 . This is the GCF
28 + 35 = 7(4 + 5) (answer)
Answer:
D
Step-by-step explanation:
This should be easy one unless you're making silly mistake like forgetting to take reciprocal of 
lets do it:
÷ first: we take the reciprocal of 3/2x now its
* 
now just multiply top and bottom by using distributive method
this is your answer.
