Which rule was used to translate the image?
right triangle lmn has vertices l(7-3), m(7-8), and
n(10.-8). the triangle is translated on the coordinate
plane so the coordinates of l'are (-1,8).
(x, y) - (x + 6, y-5)
(x, y) - (x - 6, y + 5)
(x, y) - (x + 8, y-11)
(x, y) - (x - 8. y + 11)

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

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
