A submarine that is 7500 meter below sea level surfaces at a rate of 80 meters per minute. The depth of the submarine after m minutes is given by d(m)=-7500+80m.   Graph this function.

The function can be written as follows;

d(m) = -7500+80m

m is same as x in a y = mx+c notation for a line.

80 represent the gradient m in a y = mx+c notation for a line.

-7500 represent c in  a y = mx+c notation for a line.

The function can be written as follows;

d(m) = -7500+80m

m is same as x in a y = mx+c notation for a line.

80 represent the gradient m in a y = mx+c notation for a line.

-7500 represent c in  a y = mx+c notation for a line.

 

So for the graph data is as follows.

y = d(m)

x = m

m = 80

c = -7500

 

y = 80m-7500

The range of y is -7500 to 0.

When y = -7500 then x = 0

When y = 0 then x = (0+7500)/80 = 93.75
