Choose the system of equations which matches the following graph: a) 3x + 2y = 8 6x + 4y = 20 b) 3x - 2y = 8 6x + 4y = 20 c) 3x + 2y = 8 6x - 4y = 20 d) 3x - 2y = 8 6x - 4y = 20

3x - 2y = 8

- 2y = 8 - 3x

2y = 3x - 8

y = 1.5x - 4

This is the red graph

6x - 4y = 20

- 4y = 20 - 6x

4y = 6x - 20

y = 1.5x - 5

This is the blue one.

So it must be answer d)

hi im bob : l

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
