Plz help I need help

F(x)=5/6x+3 which of the following is true

Yvaries directly as x. y =90 when x=6. find y when x=13

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
