Question

Find The equestion in slope intercept form for the line contaning the two points. (1,1 ) and ( 5,4 )

Answer 1

y2 - y1
slope = ------
x2 - x1

slope = 4 - 1
-----
5-1
slope = 3/5

y = mx + b
chooose any co-ordinate
4 =(3/5)(5) + b
4 = 15/3 + b
4 = 5 + b
4 - 5 = b
-1 = b



equation of the slope is:
y = 3/5x -1

Answer 2

5-1 IS 4

Answer 3

How would you do this one ( 8,6 ) and (- 3,6 )
