True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1

Write an equation of the line that passes through 9,2 and is parallel to the line y=5/3x+9

Which equation is true? i. 56 ÷ 4·7 = 82 ÷ (11 + 5) ii. (24 ÷ 8 + 2)3 = (42 + 9)2 neither i nor ii ii only i and ii i only
