Answer:
y = 3x
Step-by-step explanation:
A proportional relation has the equation ...
y = kx
To write the desired equation, you need to know the value of k. That can be found from the given information:
for x = 2, y = 6
6 = k·2
3 = k . . . . divide by 2
Now, we know the equation can be written ...
y = 3x
If one foot in real is 1/2 inches, then 1 inch in a blueprint is 2 feet. So a rectangle 18 by 22 inches will represent 18 * 2 by 22 * 2 feet in real. So the size of the yard is 36 by 44 feet.
