Answer:
Option B
Step-by-step explanation:
Given the corrected equations from the comment:
Y = -1/2x - 1
Y = 1/4x - 4
(I am assuming from the answer choices that the 1/2 is negative)
Use a graphing tool to graph the given equations.
When graphed, the lines pass the point (4, -3).
See graph below.
Option B should be the correct answer.
Hope this helps.

Answer:
Sachet town is 12km from the airport
Step-by-step explanation:
In this question, we are asked to calculate the distance from sachet town to the airport.
This can be calculated by referring to a diagrammatic representation. Please check attached file.
Let’s proceed with the calculations however.
From the question, we can see that we have formed a Right angled triangle from the diagram and we need to calculate the distance x.
Mathematically;
x^2 + 16^2 = 20^2
x^2 = 20^2 - 16^2
x^2 = 400 - 256
x^2 = 144
x = sq.rt of 144
x = 12km
