HELP ME PLEASE Two points A(0-4), B (2,-1)determine line AB.
a. What is the equation of the line AB? y= _1_X+_2_
What is the ponation of the line perpendicular to lineAB, passing through the point (2,-1)? y= 3 x + 4

If f(x) = 2x + 2 and g(x) = x? , what is (gºf)(2)?

Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar. consider the given table.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
