The equation of the line Tina drives back to her camera's GPS homing device is y = -x + 10.

To find the equation of the line Tina drives back to her camera's GPS homing device, we need to determine the slope and y-intercept of the line.

The answer choices are given in the form y = mx + b, where m represents the slope and b represents the y-intercept.

We can determine the slope by examining the given options.

Since the slope of a line is equal to the coefficient of x, we look for the common coefficient of x among the answer choices.

In this case, the coefficient of x is -1 in all the options.

Now we need to determine the y-intercept, which represents the value of y when x = 0.

From the options, we can see that the y-intercept is different for each equation.

Therefore, we look for the option that has the y-intercept closest to Tina's starting point, which is 10.

The equation that satisfies both conditions is y = -x + 10, so the correct answer is A).
