  1. Given the points (2, 9) and (4, 324): Homework Help ✎

    1. Write the equation of a line that passes through them.

    2. Write the equation of an exponential function with an asymptote at y = 0 that passes through them.

Using the slope-intercept form of a line and a given point, find b.

Use y = kmx and substitute the values for x and y from both points, creating two equations.

Now divide the equations and solve for m.

Now that you know m, find the value of k.

y = 0.25(6)x
