Question

Mental Math Using the slope formula, find the slope of the line through the points (0,0) and (3,6).Use pencil and paper. Explain how you can use mental math to find the slope of the line.

Answer 1

Given the points (0,0) and (3,6)

slope = y2 - y1 / x2 -x1

x1= 0, y1 = 0 , x2= 3, and y2 = 6

slope = 6 - 0 / 3 - 0

slope = 6 / 3

slope = 2

the answer is 2
