The points (6,8) and (5,5) fall on a particular line.
What is the slope of the line passing through those points?

y=3x-10

Step-by-step explanation:

To find equation of the line passing through points

and A(xa, ya) and B(xb, yb)

, we use formula: y-ya = yb-ya/xb-xa (x-xa)

In this example we have xa=

6 ,ya=

8 , xb=5

and yb=5

. So,

y-ya= yb-ya / xb-xa (x-xa)

y-8 = 5-8/ 5-6 (x-6)

y-8= 3(x-6)

y-8= 3x-18

y-8= 3x-10

y = 3x - 10

77
