Answer 1

So this is going to be a linear equation, you can tell by seeing the growth being the same between days 15 and 20 & 33 and 38. We will be using the $y=mx+b$ format, where m = slope and b = y-intercept.



The equation to solve for the slope is $\frac{y_2-y_1}{x_2-x_1}$ . You can use any two ordered pairs on this list. I'll be using 15 and 20.

$\frac{1040-815}{20-15}= \frac{225}{5} =45$

45 is the slope.


To solve for the y-intercept, plug in 45 in the m variable and any ordered pair into the x and y variable spot. For this, I'll be using (15, 815)

$815=45(15)+b \\ 815=675+b \\ 140=b$


Now putting the equation together ($y=45x+140$) we can plug in 26 into the x variable and solve.


$y=45(26)+140 \\ y=1170+140 \\ y=1310$


In short, the answer is B. 1,310 feet.
