Part B
If this is a proportional relationship, what is the constant? Write N/A if it is not proportional.
Part C
If this is a proportional relationship, write a direct proportion equation. Write N/A if it is not proportional.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb

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

answer: i think its red because you have to see what it equals to

hope that

i think you forgot some signs inbetween? if so comment and i'll try to
