Question

A plane takes off from an airport and travels at a steady speed of 350 miles per hours. Which of these graphs best represents the distance the plane is from the airport, y after traveling for x hours? Rachael has a job working at a library. The graph below shows the relationship between the number of hours. Rachael worked and the amount of money, in dollars, that Rachael earned. Select the equation that represents the amount of money, m_1 in dollars, that Rachael earned by working h hours. m = 10 k m = 9.25 k m = 9h

Explanation / Answer

25. COnsider two points as, (0,0) and (1,10).

slope = m = y2-y1 / x2-x1

Here x1 = 0 , y1 = 0, x2 = 1 and y2 = 10

m = 10 - 0 / 1 - 0 = 10/1 = 10

Therefore, m = 10k

Option a) is correct.
