Question

Wren recorded an outside temperature of -2 Fahrenheit at 8 a.m. When she checked the temperature again, it was 4 Fahrenheit at 12 p.m. If x represents the time and y represents the temperature in degrees Fahrenheit, what is the slope of the line through these two data points?

Answer 1

Rise over run. as time increases the temperature rises. starting at 8am and -2°f.
At 12pm the temperature rose to 4°f.
that's a difference of 4 hours and 6 degrees. for every hour, it rose 1.5 degrees. the slope is 1.5/1
