Find the slope of the line that passes through these two points: (- 1, 0) and (4, - 2) .

I am Lyosha [343]

Slope is vertical change over horizontal change. Since coordinates conveniently give both the horizontal and vertical coordinates of a points, we can use the coordinates of both points to differentiate, or find the change horizontally and the change vertically between the two points.

A driver is 15 feet below the surface of the water 10 seconds after he entered the water and 90 feet below the surface after 40

spin [16.1K]

Answer:

$\frac{-75ft}{30sec}$ or simplified would be $\frac{-2.5ft}{sec}$

Step-by-step explanation:

In order to calculate the rate of change, we must subtract his end position and end time by the starting position and starting time. We are using the -15 feet since it is below the surface area as the starting position and the 10 seconds as the starting time. We make each of these into a fraction and subtract like so...

$\frac{-90ft - (-15ft)}{40sec - 10sec} =$ rate of change
