Question

4. What is the slope of the line that passes through (3,2) and (5, 12)

Answer 1

There is a formula for this...
slope = (y2 - y1) / (x2 - x1)

now label your points....we can label our points as (x1,y1) and (x2,y2)
(3,2)....x1 = 3 and y1 = 2
(5,12),,x2 = 5 and y2 = 12

now we just sub our info into the slope formula
slope = (12 - 2) / (5 - 3)
slope = 10/2
slope = 5

do you understand ? If you have any questions, please ask
