Step-by-step explanation:
The answer is A. -8 I got you!!!!!
It is given in the question that in the lemon squash 2 parts concentrate is added to 5 parts of water. Thus it makes the concentrate to water ratio as 2:5 or
. Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:

Where x is the amount of water to be added, in ml (milliliters).
Cross multiplication of the above equation will give us:

Dividing both sides by 2 we will get:

Thus, if we put 90ml of concentrate in a glass, the water that should be added must be 225 ml.
The answer is y=-2x+4. The y-intercept is (0,4) and the slope is -2.
