Answer:
85
Step-by-step explanation:
You have already done half of it. Now substitute for x1 = 4 and y = 5
y - 5 = 6/7(x - 4)
Multiply everything by 7 to remove fractions
7y - 35 = 6(x - 4)
7y - 35 = 6x - 24
-6x + 7y = -24 + 35
-6x + 7y = 11
Some people prefer a positive number in front of x so multiply by -1
6x - 7y = -11
You can check the answer by testing it works for both of the original points
6x4 - 7x5 = 24 - 35 = -11 true
6x-3 - 7x-1 = -18 - -7 = -11 true
Answer:
I looked at it thoroughly and I believe your correct, I believe I have done something like this before. please tell me if I am wrong. If I am, REPORT ME so you can get your point back.

Answer:
3x -4y = 30
Step-by-step explanation:
Multiply the given equation by the least common denominator of the fractions, 6.
... (1/2x)·6 -(2/3y)·6 = 5·6
... 3x -4y = 30 . . . . . . simplify
