Question

Wren recorded an outside temperature of –2°F at 8 a.m. When she checked the temperature again, it was 4°F at 12:00 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

Explanation:

the slope of a line is the ratio "y coordinate difference / x coordinate difference" when going from one point to another.

we see that x (time in hours) changes by +4 (from 8sm to 12pm).

and y (temperature) changes by +6 (from -2 to 6).

so, the slope is 6/4 = 3/2.
