The first one because there is only one y value for every x value. you can also use the vertical line test in which you draw vertical lines and make sure the function only passes through it once at each point

Step-by-step explanation:
Each point moves to the same distance on the other side of the mirror line. The slope of the mirror line is 1, so the points move along a line perpendicular to that, one with a slope of -1. You can make sure the distances are the same by counting the grid squares.
If the price of the yogurt is directly proportional to the weight of the purchase, then it can be expressed as:
Price of yogurt = weight of purchase
With the given above, it can be further expressed as:
$5.04 = 12 oz
These can be expressed in ratio form, which is:
5.04/12
Thus, if the cup weighs 8 oz and we don't know how much it costs, then the ratio should be:
n = 8 oz, or in fractions:
n/8
After this, simply equate the two and cross multiply.
5.04 / 12 = n/8
5.04(8) = 12n
40.32 = 12n
Then solve for n:
40.32 /12 = 12n/12
n = 3.36.
Thus, the 8 oz. cup of yogurt costs $3.36.
All numbers are real numbers.
