Question

A cargo ship off the west coast of Africa sent a distress call and only provided their 10 latitude before the call cuts out. As the coast guard you need to rescue the ship. You obtain scant records of their navigational path described by the function y+20= -2x. Mark a line showing the cargo ship’s path on the map.

Answer 1

The linear function showing the cargo ship’s path on the map is given at the image at the end of the answer.

What is a linear function?

The slope-intercept representation of a linear function is given by the rule presented as follows:

y = mx + b

The coefficients of the function and their meaning are explained as follows:

• m is the slope of the function, representing the change in the output variable y when the input variable x increases by one.

• b is the y-intercept of the function, representing the numeric value of the function when the input variable x assumes a value of 0.

In this problem, the function is given as follows:

y + 20 = -2x.

In slope-intercept format, the function is:

y = -2x - 20.

This means that:

• When the longitude is of 0, the latitude is of 20. (passing through Mali).

• Due to the negative slope, the line is decreasing.

Hence the line is presented on the image given at the end of the answer.
