In the coordinate plane, points (x, 5) and (7, y) are on line k.
In the coordinate plane, points (x, 5) and (7, y) are on line k. If line k passes through the origin and has slope 5/7, then x + y =
Answer/Solution
12
Steps/Work
Line k passes through the origin and has slope 5/7 means that its equation is y=5/7*x.
Thus: (x, 5)=(7,5) and (7, y) = (7,5) --> x+y=7+5=12.
Answer: E
Thus: (x, 5)=(7,5) and (7, y) = (7,5) --> x+y=7+5=12.
Answer: E
