Blog Reflections #4

~What does the slope of a line represent
       It represents the amount that the line has changed
~How do you find the slope of a line given the equation when given the graph
       You count how many the graph has gone over and up
~Why can slope be interpreted as a rate of change
        Because it tells you how much the line has changed
~How does identifying the x and y-intercepts of a linear equation help you graph the line
        Because you already know the points that the line crosses the x and y-intercepts
~Why is the equation y=mx+b referred to as the slope intercept form of a linear equation
        Because it tells you the y-intercept and the slope so you can graph the line
~How do you graph linear equations given in slope-intercept form
        Whatever b is you put the first point there then you use the slope (m) to find the next point then graph it
~How do YOU determine which method is best to graph with comparing the 3 methods studied
         I just use slope intercept because i feel its the easiest and the best one
~Come up with a set of three functions that would be considered a family of functions. Explain.
