Answer:
y = (-1/4)x + 5
Step-by-step explanation:
y = mx + b
---------------
Solve for b first
6 = (-1/4)-4 + b
6 = 1 + b
6 - 1 = b
5 = b
y = (-1/4)x + 5
Answer:
y=-1/4x+5
Step-by-step explanation:
We need b also known as y intercept
slope-intercept form: y=mx+b
plug in x and y points
and we know m or slope is -1/4
(6)= -1/4 (-4) +b
we multiplied -1/4 by -4 which gave us +1
6= 1+b
6-1=b
5=b
Now we know what b is, so
y= -1/4x + 5

I am not sure about the formula but if you subtract 8,884 from 10,712 you get 1,828. Then, if you divide that by 4 you get 457. 457 fph(feet per hour) should be the climbers vertical speed.
