1. hiking tim began a hike near big bear lake,
california at the base of the mountain that is 7000 feet
above sea level. he is hiking at a steady rate of 5 more
feet above sea level per minute. let a be his altitude
above sea level in feet and let t be the number of
minutes he has been hiking. write an equation in
slope-intercept form that represents how many feet
above sea level tim has hiked.

Acabo de llegar de viaje. estuve en colombia y venezuela. los dos países me encantaron pero megusto mas colombia. la gente es muy amable y la comida es deliciosa. en colombia visité la sudad de cartagena, bogotá y baranquilla. en venezuela solamente estuve en la capital que es caracas. caracas no es tan bonito como bogota pero si se los recomiendo por lo menos para conocer y pasar el tiempo. el año entrante quiero viajar a españa.
