For each equation give X a value and solve for Y, do this at least two times for each equation.
Plot those dots on a graph to draw two lines.
The solution is where the two lines cross.
You will see the lines cross at (-1,-2)
The Richter scale is used to measure the intensity of an earthquake. If E, measured in joules, is the energy released during an
earthquake, then the magnitude is given by where joules.
If joules of energy are released during an earthquake, what is the magnitude of the earthquake?
