What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;

2.
A: normally we write ratios in (distance):(time) so
marie=325:20
tamara=255:15
B. proportional means that if you conver to fraction and simplify, they will be equall so
325/20=16.25/
255/15=17/1
they are not equal and therefor NOT proportional
3. so we use slope intercept form which is y=mx+b where m=slope and b=y-intercept
so we find the equation
slope=-4/3
we are given the point (0,16)
the y-intercept is where x=0
in (x,y) form, (0,16), x=0 and y=16
b=16
y=-4/3x+16
the x intercept is where the line crosses the x axis or when y=0 so set y=0 so
0=-4/3x+16
subtract 16 from both sides
-16=-4/3x
multiply both sides by -1 because I don't like negatives
16=4/3x
multiply both sides by 3
48=4x
divide both sides by 4
12=x
solution=(12,0)
it will cross at (12,0)
