Slope formula is m= (y2-y1)/(x2-x1)
We know that slope is 1. So,
(-6-1)/(x-4) = 1
Then solve for x
-6-1 = x-4
x-4 = -7
x= -7+4
x= -3
<h3>A submarine is at an elevation of -100 feet (100 feet below sea level). Let’s compare the elevations of these four people to that of the submarine:</h3>
- Clare’s elevation is greater than the elevation of the submarine. Clare is farther from sea level than the submarine.
- Andre’s elevation is less than the elevation of the submarine. Andre is farther away from sea level than the submarine.
- Han’s elevation is greater than the elevation of the submarine. Han is closer to sea level than is the submarine.
- Lin’s elevation is the same distance away from sea level as the submarine’s.
