Linear Equations in Slope-Intercept Form

Question

the function shown models the depth d (in inches) of snow on the ground during the first 9 hours of a snowstorm, where t is the time (in hours) after the snowstorm begins.

Function: d(t)=1/2t+6

Add two points on the graph, and write domain and range

Answer 1

(8,10), (10,11), (t, t/2 +6)

0<t <9 is the domain

6<d<10.5 is the range
