Answer: Correct! Incorrect. The answers are:
D: y = 5xy equals 5x This is a linear function with a slope of 5 and y-intercept of 0.
C: y = 2times⋅()^xy equals 2 times five halves to the power of x This is an exponential function with a y-intercept of 2 and a common ration of .
A: y = 25times⋅()^xy equals 25 times one-fifth to the power of This is an exponential function with a y-intercept of 25 and a common ration of .
B: y = -negative2x + 7y equals negative 2x plus 7 This is a linear function with a slope of -negative2 and y-intercept of 7. One or more of your answers are incorrect. Review the Learn It section, and then try again.
