What is the slope of the line that contains these points? x,12,13,14,,15. y,-4, 2,8,14.

Step-by-step explanation:

Let's take two points,

(12, -4) and (13, 2).

slope = (difference of y) / (difference of x)

m = (2 - - 4) / (13 - 12)

m = (2 + 4) / 1

m = 6 / 1 = 6

The slope of the line is 6.

6

Step-by-step explanation:

The slope is the change in y over the change in x

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

    = (14-8)/(15-14)

   = 6/1

we will start by setting up a proportional relationship:

$180/ 10 hours <— divide this

= $18 per hour

so to check that the equation is correct, multiply 18 by 10

$18 x 10 hours = $180

therefore, the unit rate is $18 per hour
