Variables x and y are related so that, when lg y is plotted on the vertical axis

Question:

Variables x and y are related so that, when lg y is plotted on the vertical axis and x is plotted on the horizontal axis, a straight-line graph passing though the points (6, 2) and (10, 8) is obtained.

a. Express lg y in terms of x.

b. Express y in terms of x, giving your answer in the form y = a × 10^bx.
