Without graphing, tell whether the slope of a line that models the linear relationship is positive, negative, zaro, or undefined. Then find the slope. A laptop battery has 84% power after 1 hour of use and 52% after 3 hours of use.

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
