Will Give Brainliest!!!!

Anna71 [15]

The range is Max - Min = 299 - 0 = 299

Divide this range over 10 to get 299/10 = 29.9 which rounds to 30

We'll need about 30 intervals if we want intervals of width 10

Answer: D) 25 or more

Answer:

y-4=3/2(x+4)

Step-by-step explanation:

If you plug the numbers into the equation (y-y1=m(x-x1)), you get y-4=3/2(x+4).

Given line L = ax + by + c = 0, b(its suppose to be the equal sign with the slash going thru it) 0

Serga [27]

ax + by + c = 0
by = - ax - c
y = -a/b (x) - c/b

so slope = -a/b

answer
-a/b
