Answer:

y=-x+1

Step-by-step explanation:

to get this you use the point-slope formula

y-y1=m(x-x1) - plug in the coordinates and find the slope

y--3=-1(x-4) - change the sign and solve the parentheses

y+3=-x+4 - subtract 3 from both sides to get y by itself

y=-x+1

A woman starts out walking due north for 2 miles, and then she turns due west and continues for another 2 miles. How far from he

Mrac [35]

For this case we can model the problem as a rectangle triangle.
We have:
Length of the sides of the triangle.
We want to find:
Length of the hypotenuse.
Using the Pythagorean theorem we have:
$d ^ 2 = 2 ^ 2 + 2 ^ 2
$
$d = \sqrt{2 ^ 2 + 2 ^ 2} 

d = \sqrt{4 + 4} 

d = \sqrt{8} 

d = 2\sqrt{2} 
$
Answer:
She is:
$d = 2\sqrt{2}$
miles far from her starting point
