9x+8y=15
9x+8y=30
There can't be a solution because 9x+8y equal different things in both.

For every 1/3 cup of honey, we need 1/2 cup of cream.
Since 3 times of 1/3 cup will make a 1 while cups, we multiply the ratio above by 3.
1 cup of honey will need 1/2 x 3 cups of cream.
1/2 x 3 = 3/2 = 1 1/2 cups
So 1 cup of honey will need 1/2 cup of cream.

To answer the next part, we start again from the original ratio given.
For every 1/2 cup of cream, we need 1/3 cup of honey.
We need to find 9/2 cups of cream. 9/2 cups is 9 times of 1/2 cup. So we multiply the ratio above by 9.
9/2 cups of cream will need 1/3 x 9 cups of honey.
1/3 x 9 = 3
So 9/2 cups of cream need 3 cups of honey.

Answer:
(a) 1 cup of honey needs 1/2 cup of cream
(b) 9/2 cups of cream need 3 cups of honey.

Y=-9
Input is basically your x value so output is basically your y value
So plug in -10 for x
Y=3/2(-10)+6
Y=-15+6
Y=-9
