help me revise question 3

The following data represent the amount of money an investor has in an investment account each year for 10 years. Use the data to answer questions 3-5. (Remember you are testing linear, quadratic, cubic, exponential, and logarithmic equations.) Year Value of Account e o I I 3. Use the data to draw a scatterplot. Then, choose the regression line that best fits the data and write the equation. Use x = 0 for 1990 and then count the number of years since 1990 (x = 4 for 1994, x = 5 for 1995, etc) for a better equation. Regression Formula: . y = bX + a where: b = is the slope of the line a = y-intercept Now let's find a and b: . Find b: ob= O SSx O SSxy O O O 82.5 0 58642 O 0 =710.8121212 . Find a: o a = My - bMx = 12988.6 - 710.8121212( 8.5) o a = 6946.69697 Final regression line equation: . y = 710.8121212x + 6946.69697Y, =710.8121212x - 6940.09097 This is linear which we don't want. We want it to be exponential. https://www.desmos.com/calculator/6hmp4bmyis Look at my last feedback. We want an equation in the y = ab\"x form.
