Well lets remember that a square has four sides that are all equal.
So if we know one side, we know them all!
And perimeter is all of the sides added up.
Well.. 4 sides that are all 9 meters long? here's the math!
9 + 9 + 9 + 9 = 36
Your coffee shop is 36 meters long
Good Luck! :)
So as you can see, -3 is the y-intercept. You would make a point on (-3,0) first. Then from the point, you would go up 1 and go right 2 because the slope is a positive 1/2 slope.
Since it starts at 12 and is increasing by 5 each time, the 70th term will be;
12 + 5(70)
12 + 350
362
362 is the 70th term of the sequence.
C so a proportional relationship
