Calculate the slope of the lines containing the points below. Which line has a steeper slope?


Line 1: (-2,3) and (3,1) 

Line 2: (4,5) and (2,3)


Line 1: m = -2/5

Line 2: m = 1/2

Line 2 has a steeper slope because the absolute value of Line 2's slope is larger than Line 1's.

Lisa is tracking a plant's height for her science class. When she begins tracking, the plant is 10 centimeters tall. The plant then grows 2 centimeters per week. Let x be the time (in weeks) since Lisa started tracking the plant's height, and let y be its height (in centimeters). 

a) What is the equation of the line that represents the height of the plant after x weeks?

b) After how many weeks will the plant be 200 centimeters tall?

a) y = 2x + 10

b) 95 weeks
