The graph represents a system of linear equations comparing the outside and inside temperatures y, in degrees fahrenheit, recorded at a school one day x hours after 8: 00 a. m. after how many hours were the inside and outside temperatures equal?

Hey mesquitehouse,  lets solve your question together  we know that the graph represents a system of linear equations comparing the outside and inside temperatures "y", in degrees fahrenheit, recorded at a school one day "x" hours after 8: 00 a.m.  therefore, when the "x" and "y" intercepts intersect with each other, they would represent the answer.   hope this ,                      anthrαx
