Finding Slope: Graphs, Tables, and Points

What does the 'rise over run' refer to in the context of finding slope from a graph?

• The change in x-coordinates over the change in y-coordinates

• The total distance covered on the graph

• The angle of the slope in degrees

• The change in y-coordinates over the change in x-coordinates

When calculating slope from a graph, what does a negative slope indicate?

• The line is decreasing

• The line is vertical

• The line is increasing

• The line is horizontal

In the context of slope, what does 'rise' specifically refer to?

• Change in x-coordinates

• Change in y-coordinates

• Total distance on the graph

• Angle of the slope

In a real-world graph where distance increases over time, what does a slope of 1/5 indicate?

• Every 5 miles, 1 second is taken

• Every 5 seconds, 1 mile is covered

• Every 1 mile, 5 seconds are taken

• Every 1 second, 5 miles are covered

How do you interpret a slope of 3 when calculating from a table where y is temperature and x is hours?

• Every 3 degrees, 1 hour passes

• Every 3 hours, temperature rises by 1 degree

• Temperature rises by 3 degrees every hour

• Temperature falls by 3 degrees every hour

What is the formula for calculating slope from two points?

• y2 - y1 / x2 - x1
