Answer:
y=x-4
Step-by-step explanation:
Standard form is y=mx+b
the coordinates (0, -4) tell you that the y intercept is at -4 which means b will be -4. To find slope you have to find the change in y over the change is x. 1--4=5 and 5-0=5. 5/5 is 1 so the slope, or m, is 1. x stays the same since it's the variable. it'll become y=1x-4 and since you don't have to place a coordinate of one in front of a variable, you can just write it as y=x-4
Rt-2n=y -- add 2n
Rt=y+2n -- divide by R
t=(y+2n)/R
There are 27 men in the train car.
69-15=54
54 divided by 2 = 27
The larger fractron will be the fraction with the greater numerator.
ex. 4/5 is greater than 2/5
