In math class, Julia and Ricardo are analyzing the function

Answer 1

f(x) = 2x + 3. Julia suggests that the function is a linear function because it has a constant rate of change, which is 2. Ricardo agrees and adds that the function also passes through the point (0,3), which is the y-intercept. They both conclude that the function is in the form of y = mx + b, where m is the slope and b is the y-intercept.
