on a recent scuba diving trip, kate and kara reached a depth of 130 feet. six and a half minutes later, after ascending at a constant rate they reached the surface. what is the slope, y intercept, equation, domain and range

Let x be the time and y is the depth

At x = 0 y = -130

At x= 6.5 y = 0

So the slope = (0- (-130) / ( 6.5 – 0) = 20

Y intercept b

0 = 20(6.5) + b

B= -130

The equation

Y = 20x -130

The domain all real numbers from 0 to 6.5

Range is all realnumber from -130 to 0
