For twelve people you need: 2 litres of lemon-lime soda, 1 pint of sherbet and 3 cups of ice tea.
For 36 people you need: 6 litres of lemon-lime soda, 3 pints of sherbet and 9 cups of ice.
Answer:
make the y int -4 because it passes through (0,-4). to make perpendicular, apply same slope to new equation but change sign
equation:
3x -4
Get the y alone.
-3+y=11
+3 on both sides
y=14 = y intercept
-x+y=2
Add x to both sides of the equation
Y= 2 + x
If it's for a graph then I believe you just find the slope which you can do by taking two points and plugging them into this equation y-y
/
X-X
Example: (2, 4) and (6, 7) the first number is always x and the second is always y so if you plug those in the equation would look like this....
4-7
/
2-6
That would end up being
3
- ---- aka the rate of change
4
P.s. The slash and the four dotted lines together means division. Hope this helps
