Two rovers are exploring a planet. the system of
equations below shows each rover's elevation, y, at time x. what
conclusion can you reach about the system of equations?
rover a: y= 1.9x – 8
rover b: 7y= 13.3x - 56

the slope for the rover a equation is
slope for the rover b equation.

the y-intercepts of the equations are

the system of equations has
solution(s).

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
