K, so
y=mx+b
m=slope
b=yintercept
slope=rise/run
pick 2 points
(-6,4) and (0,-1)
rise is the y value in (x,y)
from 4 to -1 it rises -5
from -6 to 0 it runs 6
rise/run=-5/6
it crosses the y axis at y=-1
b=-1
y=-5/6x-1 is equation
or
f(x)=-5/6x-1
Answer:

Step-by-step explanation:
Boys to girls
2 : 3
