Solve the problem.A deep sea diving bell is being lowered at a constant rate. After 12 minutes, the bell is at a depth of 300 feet. After 55 minutes the bell is at a depth of 1300 feet. Write a linear equation in point-slope form that gives the relationship between the time spent lowering the diving bell and the depth that the bell has reached. Round the slope to the nearest tenth.
A. y - 300 = 0.04(x - 12) or y - 1300 = 0.04(x - 55) B. y - 300 = 23.3(x - 12) or y - 1300 = 23.3(x - 55) C. y - 300 = 18.2(x - 12) or y - 1300 = 18.2(x - 55) D. y - 300 = 23.6(x - 12) or y - 1300 = 23.6(x - 55)
