Frank will use 3/8 cup of sugar, 61 1/2 cups of flour, and 9 eggs. I know this because...
3/4 divided by 2 is 3/8
20 1/2 times 3 is 61 1/2
3 times 3 is 9
Proportional because it's a straight line if you follow the graph points and it goes by 5
(-3,7)
5(-3)+2(7)=-1
-15+14=-1
Solving for y right?
2y = 3x + 4 - x
2y = 2x + 4
y = 2x + 4 over 2
y = 2 (x + 2) over 2
y = x + 2
y - 3 = 2x - 6 over 2
y - 3 = 2(x - 3) over 2
y - 3 = x - 3
y = x
x - y - 2 = 2(2x + 1)
-y - 2 = 2(2x + 1) - x
-y = 2(2x + 1) - x + 2
y = -2(2x + 1) + x - 2
