Well, bearing in mind that, a year has 12 months, so 18 months is really just 18/12 of a year, or 3/2 a year, then
The perimeter will change by the same factor Answer
Answer:
y = -1/4x + 3
Step-by-step explanation:
you got to do the inverse, so like this
y = 4x > y = -1/4x
then you do take the coordinates (4,2) and put them into place like this:
y - 2 = -1/4(x - 4) > y - 2 = -1/4x +1 (four times -1/4 = 1)
then add the -2 on both sides
y = -1/4 + 3
