We can use the equation:
f = 3.25s
3.25 is the cups of flour used for every cup of sugar.
Where 'f' represents flour and 's' represents sugar.
Answer:
Step-by-step explanation:
First of all, we need to identify the equation of the line. x and y intercepts are known, so we can quickly write the line as
That gives us the last two options. To solve it let's plug a convenient point - read: the origin - into the equation and see which one holds true. And since for obvious reason 
the valid solution is the last one.
1) The first step is to Know the condition for two lines be parallel is that have the same slope, and this form the slope given is 2, therefore the new function has its slope too
2) with the slope and the two points givens, you can find the equation
Y-Y1 = m( X-X1) , Y-6 = 2[(X-(-3)] ⇒Y-6 = 2X+6 ⇒Y = 2X+12, AND THIS IS THE EQUATION PARALLEL TO THE LINE Y = 2X-7
let the number = x
x*80/100 = 55
x = 5500/80
x=68.75
After rounding off, it will remain 68.75
