what or how would i solve the following i don't need the answer i want to do it but how would i solve this.

Water pressure (p) in the ocean is 2.3 tons per square inch at a depth (d) of 2miles and 3.45 tons per square inch at depth of 3 miles.

How do i find the linear equation using (d,p) for htese data points?

How do i find the pressure at a depth of 4miles?

Make an equation:

Pressure= m*depth + k

Put in the two values, you will have two equations. Solve for m, and k.
