Which expression is equivalent to (9x - 3 1/ + 1 3/8)

Write an equation in point-slope form for the line through the given point that has the given slope (-2,-7); m=-3/2

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
