Identift the slope and y intercept of the graph of the equation y=-4

Part a : solve - vp + 40 < 65 for v . part b : solve 7w - 3r = 15 for r show your work!

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.

Which value would be a solution for x in the inequality 47-4x< 7
