a. At what y-value does its graph intersect the y-axis?
b. At what x-value does its graph intersect the y-axis?
c. What is its slope?
d. By how much does the y-value on the line change when the x-value increases by 1 unit?
e. By how much does the y-value on the line change when the x-value decreases by 2 units?
