1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula 
to find the distance from point 
to the line Ax+By+C=0.
The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
Answer: 
.
The answer is y=4/3. Hope this helps.
Answer:
The answer is (1,0) and (2,6)
Step-by-step explanation:
y=6x-6
Pick 1 as the number for x: (6x1)-6=0
(1,0)
Pick 2: (6x2)-6=6
(2,6)
I hope this helps
Let <em>y</em> be the expression you want to differentiate:
Now,
Use the chain rule to differentiate both sides with respect to <em>x</em> :
Solve for d<em>y</em>/d<em>x</em> :
Answer:
B. The system of equations has no solution.
Step-by-step explanation:
Parallel lines never touch, in order for a system of equation to have a solution the two equations have to intersect, because parallel lines never intersect the system of equations that Presley graphed would have no solution
