Answer:
Y=1/3x
Step-by-step explanation:
1) there is no y intercept as x=0 when y=0 so that rules out y=x-2
2) next, we will use the formula for slope to find the value of m
Y2-Y1/X2-X1
Where y2=-1
Y1=0
X2=-3
X1=0
So
-1-0/-3-0=-1/-3
Aka 1/3
So y=1/3x
Hope this helps!
Four ratios:
light to dark: 4:12
dark to light: 12:4
black to white: 2:4
white to gray: 4:10
gray to white: 10:4
any of those work.
It is neccesary because you cannot subtract them without having a common denominator so you have to rename 4 1/2
