Question 1147359: On January 22, 1943, the temperature t, in degrees Fahrenheit, in spearfish, South Dakot, could be approximated by t= -2m+54, where m is the number of minutes since 9:00 a.m. that morning. Graph the equation and use the graph to estimate the temperature at 9:15 a.m.

+t+=+-2m+%2B+5+
At 9:15
+t+=+-2%2A15+%2B+54+
+t+=+-30+%2B+54+
+t+=+24+
Here's the graph:
