Write an equation that models the linear situation:The heater keeps the temperature of the pool at 78 degrees Fahrenheit all day long.Instructions:DO NOT USE ANY SPACES between variables, constants, equals signs, and operation signs.For example, DO NOT enter f(x) = 2x + 1DO ENTER: f(x)=2x+1Put parentheses around constants that are fractions like this: y=(2/3)x-(1/2)You may use decimals IF the decimal values are exact. (You cannot use 33 for 1/3 because it is not exact, but you can use 0.25 for1/4.)To write your equation, use the variables:h = amount of time since the day began (hours)T(h) temperature of the pool (Fahrenheit degrees)Equation:
