SOLUTION: Find the equation of both the line and exponential curve going through the point (2,9) with the y-intercept=5. For both curves, if x=7, find the corresponding y value and express t

Question 1129908: Find the equation of both the line and exponential curve going through the point (2,9) with the y-intercept=5. For both curves, if x=7, find the corresponding y value and express to 4 decimals.
a. Line equation (slope form) and y value for x=7
b. exponential equation (y=Ce^ax) and y value for x=7
