Question

What is the slope of the line shown below.

Answer 1

slope = (y2-y1)/(x2-x1)

(2,4)   (4,8)

 m= (8-4)/(4-2)

m = 4/2

m=2

Answer: 2

Answer 2

(2, 4) (4, 8)

you can sue the formula

y2 - y1            8 - 4                4

---------    =  -------------  =  ------------- = 4/2 = 2

x2 - x1           4 -2                 2

or there's an intuitive way to get it

(2, 4) (4, 8)

look at the y's   4 and 8  whats the space between them ?  4

looks at the x's  2 and 4  whats the space between them ?  2

so its 4/2 or 2
