During the 9 mile hike he spends 2 periods of half hour swimming = 1 hour.
actual hiking time = 3*3 = 9 hours
So total time = 9+1 = 10 hours
The point-slope form:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
We have the point (4, -6) and the slope m = 3/5. Substitute:
![y-(-6)=\dfrac{3}{5}(x-4)\\\\\boxed{y+6=\dfrac{3}{5}(x-4)}](https://tex.z-dn.net/?f=y-%28-6%29%3D%5Cdfrac%7B3%7D%7B5%7D%28x-4%29%5C%5C%5C%5C%5Cboxed%7By%2B6%3D%5Cdfrac%7B3%7D%7B5%7D%28x-4%29%7D)
Answer:
Domain -5 ≤x<1
Range -4 ≤y<7
Step-by-step explanation:
The domain is the values that x takes
X goes from -5 included to 1 not included
-5 ≤x<1
The range is the values that y takes
y goes from -4 included to 7 not included
-4 ≤y<7
Perpendicular because when you graph it the lines intersect at 90 degree angels.
