Answer:

The first one, or y= -x + 8

Step-by-step explanation:

You can rule out the last one, because there is no y intercept. If there was no y intercept, the dots would be passing through the origin (0).

The one with -8 is not right because the y intercept is positive 8. If you count on the y axis (up 8), it matches with the overall direction of the line.

The line/ slope of this scatter plot is negative, so the only one that makes sense would be the first one. Going up and from right to left is a positive slope. Going down from left to right is a negative slope.

Answer/step-by-step explanation

The soldier at point P lie on a parabola because he determined his position and distances from towns A and B through measurement of the difference in timing (phase) of radio signals received from the two towns.

This analysis of the signal time difference gives the difference in distance of the soldier at P, from the towns.

This process is known as hyperbolic navigation.

These distances of point P from towns A and B is estimated by the soldier at point P, by measuring the delay localizes the receiver to a hyperbolic line on a chart.

Two hyperbolic lines will be drawn by taking timing measurements from the

towns A and B .

Point P will be at the intersection of the lines.

These distances of point P(The soldier's positions) from town A and town B were determined using the timing of the signals received from the two towns, due to the fact that point P was on a certain hyperbola.
