Earthquakes make seismic waves through the ground. The equation y = 10 ^ x relates the height, or amplitude , in microns, of a seismic wave , y, and the power , or magnitude , x, of the ground -shaking it can cause

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
