The graph shows the relationship between the number of hours that Michelle has been driving and the distance that she has left t

nikitadnepr [17]

Answer:

(b) For each hour that Michelle drove, she traveled an additional 50 miles.

Step-by-step explanation:

Given

$(x_1,y_1) = (0,350)$ ---- start

$(x_2,y_2) = (7,0)$ --- end

Required

Which is true

(a): Journey = 6 hours

This is false, because:

$x = x_2 - x_1$

$x = 7-0$

$x = 7$ ---- 7 hours

(b): The average rate is 50 miles per hour

To do this, we calculate the slope (m) using:

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

$m = \frac{0 - 350}{7-0}$

$m = -\frac{350}{7}$

$m = -50$

This means that the rate is 50 miles driven in 1 hour.

(b) is correct

Others are incorrect
