As the graph shows,z(3,4),w(-4,1)
so,w-z(-4-3,1-4)⇒(-7,-3)
z-w(3-(-4),4-1)⇒(3+4,3)⇒(7,3).
Answer:

Step-by-step explanation:
First you can find the slope of the line that would pass through those two points using the formula:
m = 
m = 
m=5/4
Now you can just plug the slope and one of the points into point-slope form for an equation of the line that will pass through both points. You can choose either point here: I'll just use the first one.
So,

(don't leave out the parentheses!)
Answer:
Infinite solutions
Step-by-step explanation:
<em><u>Distribute the 2 to (n - 1), and distribute the 2 to (3n - 1), like so:</u></em>
2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n - 2
<em><u>Add like terms (2n and 4n):</u></em>
6n - 2 = 6n - 2
<em><u>Subtract 6n from both sides:</u></em>
-2 = -2
Since we ended up with the same term on both sides, we can't do anything else, meaning this equation has infinite solutions.
Answer:
x=15
Step-by-step explanation:
6x+15=7x
15=x
The first one is 4
