Find the slope of the ordered pair. A(4,6) B(5,8)
andrezito [222]

Answer:

<h2>The slope is 2</h2>

Step-by-step explanation:

Step one:

we are required to find the slope of the given data points

A(4,6) B(5,8)

hence the x and y values correspond to

x1=4

y1=6

x2=5

y2=8

Step two:

Required is the slope which is

slope= y2-y1/x2-x1

Slope=8-6/5-4

Slope= 2/1

<em><u>Hence the slope of the ordered pair is 2</u></em>
