8+~1-3=4
Explanation-
8-1 is the same as 8+~1 so=7
7-3=4
Answer:

Step-by-step explanation:
The equation of any line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

Two points are given: (-6,4) and (-2,2). Calculating the slope:

The equation of the line is, so far:

To calculate the value of b, we use any of the given points, for example (-6,4):


Solving:
b = 1
The equation of the line is:

We can see none of the choices is correct.
A = 5 km is your distance it is how far he traveled.
b = 3 km is your displacement it's the length in which he when north.
