<span>the equation is modelling the straight line that goes through both your given points.</span>
11 L : 20 mL
I believe but that was quick mental math
If you mean fraction,
Tom: 2/3
Sam: 1/4
Now we change the denominator.
Tom: 6/12
Sam: 3/12
6/12 + 3/12 = 9/12
9/12 can be simplified, so 3/4 of the pie was eaten.
4/4 - 3/4 = 1/4
The answer is 1/4.
This equation is in y = mx + b format, which means m is the slope.
y = 7x + 4
m = 7
The slope is 7
