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

Question:

Variables x and y are related so that, when ln y is plotted on the vertical axis and ln x is plotted on the horizontal axis, a straight-line graph passing though the points (2.5, 7.7) and (3.7, 5.3) is obtained.

a. Find the value of ln y when ln x = 0.

b. Given that y = a × x^b, find the value of a and the value of b.
