The perimeter is 20 because you just count how many squares are touching the sides
Ah, direct variation/proportion.
That is simply a linear equation with a y-intercept of 0.
So... let's solve this.
Simply put, a direct variation multiplies the x-value by a constant to get the y-value.
Let's take the point
on this graph and solve for the constant of proportionality:
We easily solve that and get our answer of
. (B)
24kx = 6
kx=6/24
kx=1/4
x=1/4/k
x = 1/4k
Answer: D) or the fourth option.
4, 3, 7 I hope this helped :)
