Each point should satisfy the equation of the line it belongs to.
This means that:
for the equation of the first line (y=x+b), the point (p,r) satisfies this equation, thus: r = p + b ....................> equation I
for the equation of the second line (y=2x+b), the point (2p,5r) satisfies this equation, thus: 5r = 4p + b ...................> equation II
Subtract equation I from equation II to eliminate the constant b:
5r-r = 4p+b-p-b
4r = 3p
Thus, r/p = 3/4
Answer:
N=1
Explanation:
If N=1 then...
5 times 1 is 5
5 is a multiple of 10
BUT it says the ONE possible solution.
So that means if I try anything else it should fail right?
let's try N=2
5 times 2 is 10
10=10 it can't be a multiple if it equals itself.
N=3
15 isn't a multiple of 10
Anything after that is too high so we found it!!
Glad I can help!!
Answer:
Inconsistent parallel lines is easiest pick k so the slopes (k) is the same as the first line.
It would be helpful to rewrite y-5x=-1 in y=mx+b where m is slope and b is y-intercept
y=5x-1 and y=kx+3 choose k=5 and you will get parallel lines and since the y intercepts are different they will be different parallel lines and inconsistent.
Now consistent intersecting lines are easy now you know the parallel solution is inconsistent so you can choose k to be what ever you want as long as it isn't 5, to make perpendicular just use -1/5.

Answer:
x=3
Explanation:
-the bisector line has to go trough the point with coordinates (3,4), see picture
-the line perpendicular and at that point (3,4) is a vertical line with the equation x=3
