Well, there's a lot of ways you could do this. Because it's multiple choice, you can just pick a pair of points and whatever equation it works in, that's your answer. In this case, it's the third one down.
If you didn't have multiple choice you would use these two formulas:
m = (y2 - y1)/(x2-x1)
y - y1 = m (x - x1)

Answer:
y = 6
Step-by-step explanation:
Just plug 11 into x then flip - 9y and 23 by picking the opposite sign so + to - or - to +
Make the equation into slope intercept form: y = mx + b
2x + y = 10
Subtract 2x
y = -2x + 10
Parallel means same slope
Y = -2x + b
Plug in the point (1,5)
5 = -2(1) + b, b = 7
Solution: y = -2x + 7
2x-2(-2+1)=4
Distribute the -2 to the numbers in parantheses.
2x+4-2=4
Combine all numbers
2x+2=4
Subtract 2 from both sides
2x=2
Then divide by two
x=1
