Brainliest + Points!<br><br> Please explain !
Morgarella [4.7K]

Answer:

A) -2/5

Step-by-step explanation:

Note that for a slope, the slope of the line is found by using the equation:

slope = (rise/run).

In this case, find two points. For example, i will use:

(0, 2) & (5, 0). (x = 0, y = 2) ; (x = 5, y = 0)

Note that "rise" = y, and "run" = x. Plug in the corresponding numbers for the corresponding points.

(2 - 0)/(0 - 5) = slope

Simplify

(2)/(-5) = slope

-(2/5) is your answer.

Note that it does not matter where the negative sign is placed.

Brian, Kelsey, and Geoff each have a remote-controlled car. They simultaneously started their cars and drove them in a straight
jasenka [17]

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the Brian, Kelsey, and Geoff each have a remote-controlled car. They simultaneously started their cars and drove them in a straight line away from a motion sensor.

It means they are travelling at a constant rate.

Slope formula:

m=\frac{y_2-y_1}{x_2-x_1}

From the given table it is clear that the of Brian's car from the sensor is 34 at 1 sec and 38 at 3 sec. The rate of change is

m=\frac{38-34}{3-1}=2

It means the Brian's car traveled at the rate of 2 cm per sec.

From the given table it is clear that the of Brian's car from the sensor is 27 at 1 sec and 31 at 3 sec. The rate of change is

m=\frac{31-27}{3-1}=2

It means the Kelsey's car traveled at the rate of 2 cm per sec.

From the given table it is clear that the of Brian's car from the sensor is 27 at 1 sec and 33 at 3 sec. The rate of change is

m=\frac{33-27}{3-1}=3

It means the Geoff's car traveled at the rate of 3 cm per sec.

Since Brian's and Geoff's car traveled at the same rate, therefore option 1 is correct.
