An oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours. Which graph has a slope that best represents this rate?

Graph G

Step-by-step explanation:

The graphs are attached

Given that the oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours, hence the rate at which the shaft drills = 7 meter / 2 hours = 3.5 meters per hour

Since the drill goes into the ground, hence the rate is negative that is -3.5 meters per secong

The slope (rate of change) of a line (m) is given by:

a) For graph F, the line passes through the point (0,0) and (10, -20). Hence:

b) For graph G, the line passes through the point (0,0) and (10, -70). Hence:

c) For graph H, the line passes through the point (0,0) and (10, -35). Hence:

d) For graph J, the line passes through the point (0,-3.5) and (10, -3.5). Hence:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
