- Changing the value of
bin cellW6affects the values in the table. Describe the relationship between the values in the X and Y columns whenmis left as 1 and:

b= 0

b= 3

b= -5

- Increasing or decreasing the value of
balso affects the graph. Describe the change in the graph whenm= 1 and:

bis changed from 0 to 3

bis changed from 0 to 1/2

bis changed from 0 to -6

- Find the y-intercept for each of the following:

y = 3x+2

y = -2x+5

y = x-8

- In the equation
y = mx+b,maffects the steepness and direction of the line. What doesbcontrol?

- Write the equation of a line:

with slope 4 and y-intercept 2

with slope -6 and y-intercept 6

with slope 0 and y-intercept -1

with slope 2/3 and y-intercept 0
