Question

angel started hiking at an elevation of 2 meters above sea level. he hiked up at a rate of 3 meters per minute. the graph below represents the relationship between the number of minutes and the elevation. use your equation to help you find the elevation after 6 minutes. the number of minutes is represented by x, so start by substituting 6 for x in the equation. the equation is e = 2 + 3x, then e = 2 + 3 · \square

Explanation:

Step1: Substitute x=6 into equation

$e = 2 + 3 \cdot 6$

Step2: Calculate the product first

$3 \cdot 6 = 18$

Step3: Add the initial elevation

$e = 2 + 18$

Answer:

$e = 20$
The elevation after 6 minutes is 20 meters above sea level.
