If the point (7,3) is on the graph of an equation, which statement must be
true?
A. The values x = 7 and y= 3 are the only values that make the
equation true.
B. The values x = 3 and y = 7 make the equation true.
OO
c. The values x = 7 and y = 3 make the equation true.
O
D. There are solutions to the equation for the values x = 7 and x = 3.

c

Step-by-step explanation:

the answer is c because they cannot be the only thing that makes it true because it is just one point you need several for an equation so yes it is part of the equation but it is not the only part

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
