- Changing the value of
min cellW4affects the values in the Y column of the table. Describe the relationship between the X and Y values:

when m = 1

when m = 2

when m = -4

- As the value of
mchanges, there is also an effect on the graph. Describe the direction and steepness of the line:

when

mis small

whenmis large

whenmis negative

- What command in cell Y1 would produce a graph with a slope of 5?

- What equation produces a graph that is the reflection of the graph of
y = 3xin the x-axis?

- The point where the graph of a function meets the y axis is called the y-intercept. What is the y-intercept of each of the following:

y = 3x

y = 5x

y = -6x

- Why is the y-intercept of functions of the form
y = mxalways 0?
