Which numbers are a distance of 6 units from 2 on the number line? select the location on the number line to plot each point.

-4 and 8

2-6=-4 & 2+6=8

I'm pretty sure this is corret.

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
