Answer 1

F, G, H

Explanation:

$9/6 = $1.5

$6/4 = $1.5

The price is $1.50 per notebook.

Every point on the graph must have a y-coordinate that is 1.5 times the x-coordinate.

The function is y = 1.5x

F(3,4.50) 3 * 1.5 = 4.5 Yes

G(8,12) 8 * 1.5 = 12 Yes

H(7,10.50) 7 * 1.5 = 10.5 Yes

J(12,16) 12 * 1.5 = 18 No
