To find slope subtract the two points in the coordinate (y). We have 8 and 4 so subtract those two. You get 8-4=4. Now start from the same coordinate expect this time subtract (x). Which is 9-3=6. You have 4/6 simplify and you get 2/3. Your slope is 2/3. Hope this helps
The time from 1 to 4 is 3 hours. (1-2, 2-3, 3-4).
The height you climbed is 1200 feet.
1200/3 is 400.
Your final answer should be 400ft/h
The slope of line T is -1/5, because perpendicular lines have opposite reciprocal slopes, meaning the opposite sign (positive or negative) and flipped (whole number becomes a fraction).
The last one because its like turning it into a fraction but your putting as a desamile or how ever you spell it
